+[FAISS](https://github.com/facebookresearch/faiss) is a library for efficient similarity search and clustering of dense vectors. It is designed to work with large-scale datasets and provides a high-performance search engine for vector data. FAISS is optimized for memory usage and search speed, making it an excellent choice for production environments.
+

+]
+m.add(messages, user_id="alice", metadata={"category": "movies"})
+```
+
+### Installation
+
+To use FAISS in your mem0 project, you need to install the appropriate FAISS package for your environment:
+
+```bash
+# For CPU version
+pip install faiss-cpu
+
+# For GPU version (requires CUDA)
+pip install faiss-gpu
+```
+
+### Config
+
+Here are the parameters available for configuring FAISS:
+
+| Parameter | Description | Default Value |
+| --- | --- | --- |
+| `collection_name` | The name of the collection | `mem0` |
+| `path` | Path to store FAISS index and metadata | `/tmp/faiss/<collection_name>` |
+| `distance_strategy` | Distance metric strategy to use (options: 'euclidean', 'inner_product', 'cosine') | `euclidean` |
+| `normalize_L2` | Whether to normalize L2 vectors (only applicable for euclidean distance) | `False` |
+
+### Performance Considerations
+
+FAISS offers several advantages for vector search:
+
+1. **Efficiency**: FAISS is optimized for memory usage and speed, making it suitable for large-scale applications.
+2. **Offline Support**: FAISS works entirely locally, with no need for external servers or API calls.
+3. **Storage Options**: Vectors can be stored in-memory for maximum speed or persisted to disk.
+4. **Multiple Index Types**: FAISS supports different index types optimized for various use cases (though mem0 currently uses the basic flat index).
+
+### Distance Strategies
+
+FAISS in mem0 supports three distance strategies:
+
+- **euclidean**: L2 distance, suitable for most embedding models
+- **inner_product**: Dot product similarity, useful for some specialized embeddings
+- **cosine**: Cosine similarity, best for comparing semantic similarity regardless of vector magnitude
+
+When using `cosine` or `inner_product` with normalized vectors, you may want to set `normalize_L2=True` for better results.

+title: Email Processing with Mem0
+---
+
+This guide demonstrates how to build an intelligent email processing system using Mem0's memory capabilities. You'll learn how to store, categorize, retrieve, and analyze emails to create a smart email management solution.
+
+## Overview
+
+Email overload is a common challenge for many professionals. By leveraging Mem0's memory capabilities, you can build an intelligent system that:
+
+- Stores emails as searchable memories
+- Categorizes emails automatically
+- Retrieves relevant past conversations
+- Prioritizes messages based on importance
+- Generates summaries and action items
+
+## Setup
+
+Before you begin, ensure you have the required dependencies installed:
+
+```bash
+pip install mem0ai openai
+```
+
+## Implementation
+

+---
+
+# Building Voice Agents with Memory using Mem0 and OpenAI Agents SDK
+
+This guide demonstrates how to combine OpenAI's Agents SDK for voice applications with Mem0's memory capabilities to create a voice assistant that remembers user preferences and past interactions.
+
+## Prerequisites
+
+Before you begin, make sure you have:
+
+1. Installed OpenAI Agents SDK with voice dependencies:
+```bash
+pip install 'openai-agents[voice]'
+```
+
+2. Installed Mem0 SDK:
+```bash
+pip install mem0ai
+```
+
+3. Installed other required dependencies:
+```bash
+pip install numpy sounddevice pydantic
+```
+
+4. Set up your API keys:
+   - OpenAI API key for the Agents SDK
+   - Mem0 API key from the Mem0 Platform
+
+## Code Breakdown
+
+Let's break down the key components of this implementation:
+
+### 1. Setting Up Dependencies and Environment
+
+```python
+# OpenAI Agents SDK imports
+from agents import (
+    Agent,
+    function_tool
+)
+from agents.voice import (
+    AudioInput,
+    SingleAgentVoiceWorkflow,
+    VoicePipeline
+)
+from agents.extensions.handoff_prompt import prompt_with_handoff_instructions
+
+# Mem0 imports
+from mem0 import AsyncMemoryClient
+
+# Set up API keys (replace with your actual keys)
+os.environ["OPENAI_API_KEY"] = "your-openai-api-key"
+os.environ["MEM0_API_KEY"] = "your-mem0-api-key"
+
+# Define a global user ID for simplicity
+USER_ID = "voice_user"
+
+# Initialize Mem0 client
+mem0_client = AsyncMemoryClient()
+```
+
+This section handles:
+- Importing required modules from OpenAI Agents SDK and Mem0
+- Setting up environment variables for API keys
+- Defining a simple user identification system (using a global variable)
+- Initializing the Mem0 client that will handle memory operations
+
+### 2. Memory Tools with Function Decorators
+
+The `@function_tool` decorator transforms Python functions into callable tools for the OpenAI agent. Here are the key memory tools:
+
+#### Storing User Memories
+
+```python
+import logging
+
+# Set up logging at the top of your file
+logging.basicConfig(
+    level=logging.DEBUG,
+    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
+    force=True
+)
+logger = logging.getLogger("memory_voice_agent")
+
+# Then use logger in your function tools
+@function_tool
+async def save_memories(
+    memory: str
+) -> str:
+    """Store a user memory in memory."""
+    # This will be visible in your console
+    logger.debug(f"Saving memory: {memory} for user {USER_ID}")
+    
+    # Store the preference in Mem0
+    memory_content = f"User memory - {memory}"
+    await mem0_client.add(
+        memory_content,
+        user_id=USER_ID,
+    )
+
+    return f"I've saved your memory: {memory}"
+```
+
+This function:
+- Takes a memory string
+- Creates a formatted memory string
+- Stores it in Mem0 using the `add()` method
+- Includes metadata to categorize the memory for easier retrieval
+- Returns a confirmation message that the agent will speak
+
+#### Finding Relevant Memories
+
+```python
+@function_tool
+async def search_memories(
+    query: str
+) -> str:
+    """
+    Find memories relevant to the current conversation.
+    Args:
+        query: The search query to find relevant memories
+    """
+    print(f"Finding memories related to: {query}")
+    results = await mem0_client.search(
+        query,
+        user_id=USER_ID,
+        limit=5,
+        threshold=0.7,  # Higher threshold for more relevant results
+        output_format="v1.1"
+    )
+    
+    # Format and return the results
+    if not results.get('results', []):
+        return "I don't have any relevant memories about this topic."
+    
+    memories = [f"• {result['memory']}" for result in results.get('results', [])]
+    return "Here's what I remember that might be relevant:\n" + "\n".join(memories)
+```
+
+This tool:
+- Takes a search query string
+- Passes it to Mem0's semantic search to find related memories
+- Sets a threshold for relevance to ensure quality results
+- Returns a formatted list of relevant memories or a default message
+
+### 3. Creating the Voice Agent
+
+```python
+def create_memory_voice_agent():
+    # Create the agent with memory-enabled tools
+    agent = Agent(
+        name="Memory Assistant",
+        instructions=prompt_with_handoff_instructions(
+            """You're speaking to a human, so be polite and concise.
+            Always respond in clear, natural English.
+            You have the ability to remember information about the user.
+            Use the save_memories tool when the user shares an important information worth remembering.
+            Use the search_memories tool when you need context from past conversations or user asks you to recall something.
+            """,
+        ),
+        model="gpt-4o",
+        tools=[save_memories, search_memories],
+    )
+    
+    return agent
+```
+
+This function:
+- Creates an OpenAI Agent with specific instructions
+- Configures it to use gpt-4o (you can use other models)
+- Registers the memory-related tools with the agent
+- Uses `prompt_with_handoff_instructions` to include standard voice agent behaviors
+
+### 4. Microphone Recording Functionality
+
+```python
+async def record_from_microphone(duration=5, samplerate=24000):
+    """Record audio from the microphone for a specified duration."""
+    print(f"Recording for {duration} seconds...")
+    
+    # Create a buffer to store the recorded audio
+    frames = []
+    
+    # Callback function to store audio data
+    def callback(indata, frames_count, time_info, status):
+        frames.append(indata.copy())
+    
+    # Start recording
+    with sd.InputStream(samplerate=samplerate, channels=1, callback=callback, dtype=np.int16):
+        await asyncio.sleep(duration)
+    
+    # Combine all frames into a single numpy array
+    audio_data = np.concatenate(frames)
+    return audio_data
+```
+
+This function:
+- Creates a simple asynchronous microphone recording function
+- Uses the sounddevice library to capture audio input
+- Stores frames in a buffer during recording
+- Combines frames into a single numpy array when complete
+- Returns the audio data for processing
+
+### 5. Main Loop and Voice Processing
+
+```python
+async def main():
+    # Create the agent
+    agent = create_memory_voice_agent()
+    
+    # Set up the voice pipeline
+    pipeline = VoicePipeline(
+        workflow=SingleAgentVoiceWorkflow(agent)
+    )
+    
+    # Configure TTS settings
+    pipeline.config.tts_settings.voice = "alloy"
+    pipeline.config.tts_settings.speed = 1.0
+    
+    try:
+        while True:
+            # Get user input
+            print("\nPress Enter to start recording (or 'q' to quit)...")
+            user_input = input()
+            if user_input.lower() == 'q':
+                break
+            
+            # Record and process audio
+            audio_data = await record_from_microphone(duration=5)
+            audio_input = AudioInput(buffer=audio_data)
+            result = await pipeline.run(audio_input)
+            
+            # Play response and handle events
+            player = sd.OutputStream(samplerate=24000, channels=1, dtype=np.int16)
+            player.start()
+            
+            agent_response = ""
+            print("\nAgent response:")
+            
+            async for event in result.stream():
+                if event.type == "voice_stream_event_audio":
+                    player.write(event.data)
+                elif event.type == "voice_stream_event_content":
+                    content = event.data
+                    agent_response += content

+                        metadata={"type": "agent_response"}
+                    )
+                except Exception as e:

+    
+    except KeyboardInterrupt:
+        print("\nExiting...")
+```
+
+This main function orchestrates the entire process:
+1. Creates the memory-enabled voice agent
+2. Sets up the voice pipeline with TTS settings
+3. Implements an interactive loop for recording and processing voice input
+4. Handles streaming of response events (both audio and text)
+5. Automatically saves the agent's responses to memory
+6. Includes proper error handling and exit mechanisms

+    asyncio.run(main())

+
+## Key Features of This Implementation
+
+This implementation offers several key features:
+
+1. **Simplified User Management**: Uses a global `USER_ID` variable for simplicity, but can be extended to manage multiple users.
+
+2. **Real Microphone Input**: Includes a `record_from_microphone()` function that captures actual voice input from your microphone.
+
+3. **Interactive Voice Loop**: Implements a continuous interaction loop, allowing for multiple back-and-forth exchanges.
+
+4. **Memory Management Tools**:
+   - `save_memories`: Stores user memories in Mem0
+   - `search_memories`: Searches for relevant past information
+
+5. **Voice Configuration**: Demonstrates how to configure TTS settings for the voice response.
+
+## Running the Example
+
+To run this example:
+
+1. Replace the placeholder API keys with your actual keys
+2. Make sure your microphone is properly connected
+3. Run the script with Python 3.8 or newer
+4. Press Enter to start recording, then speak your request
+5. Press 'q' to quit the application
+
+The agent will listen to your request, process it through the OpenAI model, utilize Mem0 for memory operations as needed, and respond both through text output and voice speech.
+
+## Best Practices for Voice Agents with Memory
+
+1. **Optimizing Memory for Voice**: Keep memories concise and relevant for voice responses.
+
+2. **Forgetting Mechanism**: Implement a way to delete or expire memories that are no longer relevant.
+
+3. **Context Preservation**: Store enough context with each memory to make retrieval effective.
+
+4. **Error Handling**: Implement robust error handling for memory operations, as voice interactions should continue smoothly even if memory operations fail.
+
+## Conclusion
+
+By combining OpenAI's Agents SDK with Mem0's memory capabilities, you can create voice agents that maintain persistent memory of user preferences and past interactions. This significantly enhances the user experience by making conversations more natural and personalized.
+
+As you build your voice application, experiment with different memory strategies and filtering approaches to find the optimal balance between comprehensive memory and efficient retrieval for your specific use case.
+
+## Debugging Function Tools
+
+When working with the OpenAI Agents SDK, you might notice that regular `print()` statements inside `@function_tool` decorated functions don't appear in your console output. This is because the Agents SDK captures and redirects standard output when executing these functions.
+
+To effectively debug your function tools, use Python's `logging` module instead:
+
+```python
+import logging
+
+# Set up logging at the top of your file
+logging.basicConfig(
+    level=logging.DEBUG,
+    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
+    force=True
+)
+logger = logging.getLogger("memory_voice_agent")
+
+# Then use logger in your function tools
+@function_tool
+async def save_memories(
+    memory: str
+) -> str:
+    """Store a user memory in memory."""
+    # This will be visible in your console
+    logger.debug(f"Saving memory: {memory} for user {USER_ID}")
+    
+    # Rest of your function...
+```

+title: ElevenLabs
+---
+
+Create voice-based conversational AI agents with memory capabilities by integrating ElevenLabs and Mem0. This integration enables persistent, context-aware voice interactions that remember past conversations.
+
+## Overview
+
+In this guide, we'll build a voice agent that:
+1. Uses ElevenLabs Conversational AI for voice interaction
+2. Leverages Mem0 to store and retrieve memories from past conversations
+3. Provides personalized responses based on user history
+
+## Setup and Configuration
+
+Install necessary libraries:
+
+```bash
+pip install elevenlabs mem0 python-dotenv
+```
+
+Configure your environment variables:
+
+<Note>You'll need both an ElevenLabs API key and a Mem0 API key to use this integration.</Note>
+
+```bash
+# Create a .env file with these variables
+AGENT_ID=your-agent-id
+USER_ID=unique-user-identifier
+ELEVENLABS_API_KEY=your-elevenlabs-api-key
+MEM0_API_KEY=your-mem0-api-key
+```
+
+## Integration Code Breakdown
+
+Let's break down the implementation into manageable parts:
+
+### 1. Imports and Environment Setup
+
+First, we import required libraries and set up the environment:
+
+```python
+import os
+import signal
+import sys
+from mem0 import AsyncMemoryClient
+
+from elevenlabs.client import ElevenLabs
+from elevenlabs.conversational_ai.conversation import Conversation
+from elevenlabs.conversational_ai.default_audio_interface import DefaultAudioInterface
+from elevenlabs.conversational_ai.conversation import ClientTools
+```
+
+These imports provide:
+- Standard Python libraries for system operations and signal handling
+- `AsyncMemoryClient` from Mem0 for memory operations
+- ElevenLabs components for voice interaction
+
+### 2. Environment Variables and Validation
+
+Next, we validate the required environment variables:
+
+```python
+def main():
+    # Required environment variables
+    AGENT_ID = os.environ.get('AGENT_ID')
+    USER_ID = os.environ.get('USER_ID')
+    API_KEY = os.environ.get('ELEVENLABS_API_KEY')
+    MEM0_API_KEY = os.environ.get('MEM0_API_KEY')
+
+    # Validate required environment variables
+    if not AGENT_ID:
+        sys.stderr.write("AGENT_ID environment variable must be set\n")
+        sys.exit(1)
+
+    if not USER_ID:
+        sys.stderr.write("USER_ID environment variable must be set\n")
+        sys.exit(1)
+
+    if not API_KEY:
+        sys.stderr.write("ELEVENLABS_API_KEY not set, assuming the agent is public\n")
+
+    if not MEM0_API_KEY:
+        sys.stderr.write("MEM0_API_KEY environment variable must be set\n")
+        sys.exit(1)
+
+    # Set up Mem0 API key in the environment
+    os.environ['MEM0_API_KEY'] = MEM0_API_KEY
+```
+
+This section:
+- Retrieves required environment variables
+- Performs validation to ensure required variables are present
+- Exits the application with an error message if required variables are missing
+- Sets the Mem0 API key in the environment for the Mem0 client to use
+
+### 3. Client Initialization
+
+Initialize both the ElevenLabs and Mem0 clients:
+
+```python
+    # Initialize ElevenLabs client
+    client = ElevenLabs(api_key=API_KEY)
+
+    # Initialize memory client and tools
+    client_tools = ClientTools()
+    mem0_client = AsyncMemoryClient()
+```
+
+Here we:
+- Create an ElevenLabs client with the API key
+- Initialize a ClientTools object for registering function tools
+- Create an AsyncMemoryClient instance for Mem0 interactions
+
+### 4. Memory Function Definitions
+
+Define the two key memory functions that will be registered as tools:
+
+```python
+    # Define memory-related functions for the agent
+    async def add_memories(parameters):
+        """Add a message to the memory store"""
+        message = parameters.get("message")
+        await mem0_client.add(
+            messages=message, 
+            user_id=USER_ID, 
+            output_format="v1.1", 
+            version="v2"
+        )
+        return "Memory added successfully"
+
+    async def retrieve_memories(parameters):
+        """Retrieve relevant memories based on the input message"""
+        message = parameters.get("message")
+
+        # Set up filters to retrieve memories for this specific user
+        filters = {
+            "AND": [
+                {
+                    "user_id": USER_ID
+                }
+            ]
+        }
+
+        # Search for relevant memories using the message as a query
+        results = await mem0_client.search(
+            query=message,
+            version="v2", 
+            filters=filters
+        )
+
+        # Extract and join the memory texts
+        memories = ' '.join([result["memory"] for result in results])
+        print("[ Memories ]", memories)
+
+        if memories:
+            return memories
+        return "No memories found"
+```
+
+These functions:
+
+#### `add_memories`:
+- Takes a message parameter containing information to remember
+- Stores the message in Mem0 using the `add` method
+- Associates the memory with the specific USER_ID
+- Returns a success message to the agent
+
+#### `retrieve_memories`:
+- Takes a message parameter as the search query
+- Sets up filters to only retrieve memories for the current user
+- Uses semantic search to find relevant memories
+- Joins all retrieved memories into a single text
+- Prints retrieved memories to the console for debugging
+- Returns the memories or a "No memories found" message if none are found
+
+### 5. Registering Memory Functions as Tools
+
+Register the memory functions with the ElevenLabs ClientTools system:
+
+```python
+    # Register the memory functions as tools for the agent
+    client_tools.register("addMemories", add_memories, is_async=True)
+    client_tools.register("retrieveMemories", retrieve_memories, is_async=True)
+```
+
+This allows the ElevenLabs agent to:
+- Access these functions through function calling
+- Wait for asynchronous results (is_async=True)
+- Call these functions by name ("addMemories" and "retrieveMemories")
+
+### 6. Conversation Setup
+
+Configure the conversation with ElevenLabs:
+
+```python
+    # Initialize the conversation
+    conversation = Conversation(
+        client,
+        AGENT_ID,
+        # Assume auth is required when API_KEY is set
+        requires_auth=bool(API_KEY),
+        audio_interface=DefaultAudioInterface(),
+        client_tools=client_tools,
+        callback_agent_response=lambda response: print(f"Agent: {response}"),
+        callback_agent_response_correction=lambda original, corrected: print(f"Agent: {original} -> {corrected}"),
+        callback_user_transcript=lambda transcript: print(f"User: {transcript}"),
+        # callback_latency_measurement=lambda latency: print(f"Latency: {latency}ms"),
+    )
+```
+
+This sets up the conversation with:
+- The ElevenLabs client and Agent ID
+- Authentication requirements based on API key presence
+- DefaultAudioInterface for handling audio I/O
+- The client_tools with our memory functions
+- Callback functions for:
+  - Displaying agent responses
+  - Showing corrected responses (when the agent self-corrects)
+  - Displaying user transcripts for debugging
+  - (Commented out) Latency measurements
+
+### 7. Conversation Management
+
+Start and manage the conversation:
+
+```python
+    # Start the conversation
+    print(f"Starting conversation with user_id: {USER_ID}")
+    conversation.start_session()
+
+    # Handle Ctrl+C to gracefully end the session
+    signal.signal(signal.SIGINT, lambda sig, frame: conversation.end_session())
+
+    # Wait for the conversation to end and get the conversation ID
+    conversation_id = conversation.wait_for_session_end()
+    print(f"Conversation ID: {conversation_id}")
+
+
+if __name__ == '__main__':
+    main()
+```
+
+This final section:
+- Prints a message indicating the conversation has started
+- Starts the conversation session
+- Sets up a signal handler to gracefully end the session on Ctrl+C
+- Waits for the session to end and gets the conversation ID
+- Prints the conversation ID for reference
+
+## Memory Tools Overview
+
+This integration provides two key memory functions to your conversational AI agent:
+
+### 1. Adding Memories (`addMemories`)
+
+The `addMemories` tool allows your agent to store important information during a conversation, including:
+- User preferences
+- Important facts shared by the user
+- Decisions or commitments made during the conversation
+- Action items to follow up on
+
+When the agent identifies information worth remembering, it calls this function to store it in the Mem0 database with the appropriate user ID.
+
+#### How it works:
+1. The agent identifies information that should be remembered
+2. It formats the information as a message string
+3. It calls the `addMemories` function with this message
+4. The function stores the memory in Mem0 linked to the user's ID
+5. Later conversations can retrieve this memory
+
+#### Example usage in agent prompt:
+```
+When the user shares important information like preferences or personal details, 
+use the addMemories function to store this information for future reference.
+```
+
+### 2. Retrieving Memories (`retrieveMemories`)
+
+The `retrieveMemories` tool allows your agent to search for and retrieve relevant memories from previous conversations. The agent can:
+- Search for context related to the current topic
+- Recall user preferences
+- Remember previous interactions on similar topics
+- Create continuity across multiple sessions
+
+#### How it works:
+1. The agent needs context for the current conversation
+2. It calls `retrieveMemories` with the current conversation topic or question
+3. The function performs a semantic search in Mem0
+4. Relevant memories are returned to the agent
+5. The agent incorporates these memories into its response
+
+#### Example usage in agent prompt:
+```
+At the beginning of each conversation turn, use retrieveMemories to check if we've 
+discussed this topic before or if the user has shared relevant preferences.
+```
+
+## Configuring Your ElevenLabs Agent
+
+To enable your agent to effectively use memory:
+
+1. Add function calling capabilities to your agent in the ElevenLabs platform:
+   - Go to your agent settings in the ElevenLabs platform
+   - Navigate to the "Tools" section
+   - Enable function calling for your agent
+   - Add the memory tools as described below
+
+2. Add the `addMemories` and `retrieveMemories` tools to your agent with these specifications:
+
+For `addMemories`:
+```json
+{
+  "name": "addMemories",
+  "description": "Stores important information from the conversation to remember for future interactions",
+  "parameters": {
+    "type": "object",
+    "properties": {
+      "message": {
+        "type": "string",
+        "description": "The important information to remember"
+      }
+    },
+    "required": ["message"]
+  }
+}
+```
+
+For `retrieveMemories`:
+```json
+{
+  "name": "retrieveMemories",
+  "description": "Retrieves relevant information from past conversations",
+  "parameters": {
+    "type": "object",
+    "properties": {
+      "message": {
+        "type": "string",
+        "description": "The query to search for in past memories"
+      }
+    },
+    "required": ["message"]
+  }
+}
+```
+
+3. Update your agent's prompt to instruct it to use these memory functions. For example:
+
+```
+You are a helpful voice assistant that remembers past conversations with the user.
+
+You have access to memory tools that allow you to remember important information:
+- Use retrieveMemories at the beginning of the conversation to recall relevant context from prior conversations
+- Use addMemories to store new important information such as:
+  * User preferences
+  * Personal details the user shares
+  * Important decisions made
+  * Tasks or follow-ups promised to the user
+
+Before responding to complex questions, always check for relevant memories first.
+When the user shares important information, make sure to store it for future reference.
+```
+
+## Example Conversation Flow
+
+Here's how a typical conversation with memory might flow:
+
+1. **User speaks**: "Hi, do you remember my favorite color?"
+
+2. **Agent retrieves memories**:
+   ```python
+   # Agent calls retrieve_memories
+   memories = retrieve_memories({"message": "user's favorite color"})
+   # If found: "The user's favorite color is blue"
+   ```
+
+3. **Agent processes with context**:
+   - If memories found: Prepares a personalized response
+   - If no memories: Prepares to ask and store the information
+
+4. **Agent responds**:
+   - With memory: "Yes, your favorite color is blue!"
+   - Without memory: "I don't think you've told me your favorite color before. What is it?"
+
+5. **User responds**: "It's actually green."
+
+6. **Agent stores new information**:
+   ```python
+   # Agent calls add_memories
+   add_memories({"message": "The user's favorite color is green"})
+   ```
+
+7. **Agent confirms**: "Thanks, I'll remember that your favorite color is green."
+
+## Example Use Cases
+
+- **Personal Assistant** - Remember user preferences, past requests, and important dates
+  ```
+  User: "What restaurants did I say I liked last time?"
+  Agent: *retrieves memories* "You mentioned enjoying Bella Italia and The Golden Dragon."
+  ```
+
+- **Customer Support** - Recall previous issues a customer has had
+  ```
+  User: "I'm having that same problem again!"
+  Agent: *retrieves memories* "Is this related to the login issue you reported last week?"
+  ```
+
+- **Educational AI** - Track student progress and tailor teaching accordingly
+  ```
+  User: "Let's continue our math lesson."
+  Agent: *retrieves memories* "Last time we were working on quadratic equations. Would you like to continue with that?"
+  ```
+
+- **Healthcare Assistant** - Remember symptoms, medications, and health concerns
+  ```
+  User: "Have I told you about my allergy medication?"
+  Agent: *retrieves memories* "Yes, you mentioned you're taking Claritin for your pollen allergies."
+  ```
+
+## Troubleshooting
+
+- **Missing API Keys**: 
+  - Error: "API_KEY environment variable must be set"
+  - Solution: Ensure all environment variables are set correctly in your .env file or system environment
+  
+- **Connection Issues**:
+  - Error: "Failed to connect to API"
+  - Solution: Check your network connection and API key permissions. Verify the API keys are valid and have the necessary permissions.
+  
+- **Empty Memory Results**:
+  - Symptom: Agent always responds with "No memories found"
+  - Solution: This is normal for new users. The memory database builds up over time as conversations occur. It's also possible your query isn't semantically similar to stored memories - try different phrasing.
+  
+- **Agent Not Using Memories**:
+  - Symptom: The agent retrieves memories but doesn't incorporate them in responses
+  - Solution: Update the agent's prompt to explicitly instruct it to use the retrieved memories in its responses
+
+## Conclusion
+
+By integrating ElevenLabs Conversational AI with Mem0, you can create voice agents that maintain context across conversations and provide personalized responses based on user history. This powerful combination enables:
+
+- More natural, context-aware conversations
+- Personalized user experiences that improve over time
+- Reduced need for users to repeat information
+- Long-term relationship building between users and AI agents

+## Code Breakdown
+
+Let's break down the key components of this implementation:
+
+### 1. Setting Up Dependencies and Environment
+
+```python
+import asyncio
+import logging
+import os
+from typing import List, Dict, Any, Annotated
+
+import aiohttp
+from dotenv import load_dotenv
+from livekit.agents import (
+    AutoSubscribe,

+    llm,
+    metrics,
+)
+from livekit import rtc, api
+from livekit.agents.pipeline import VoicePipelineAgent
+from livekit.plugins import deepgram, openai, silero
+from mem0 import AsyncMemoryClient
+
+# Load environment variables
+load_dotenv()
+
+# Configure logging
+logger = logging.getLogger("memory-assistant")
+logger.setLevel(logging.INFO)
+
+# Define a global user ID for simplicity
+USER_ID = "voice_user"
+
+# Initialize Mem0 client
+mem0 = AsyncMemoryClient()
+```
+
+This section handles:
+- Importing required modules
+- Loading environment variables
+- Setting up logging
+- Extracting user identification
+- Initializing the Mem0 client
+
+### 2. Memory Enrichment Function
+
+```python
+async def _enrich_with_memory(agent: VoicePipelineAgent, chat_ctx: llm.ChatContext):
+    """Add memories and Augment chat context with relevant memories"""
+    if not chat_ctx.messages:
+        return
+    
+    # Store user message in Mem0
+    user_msg = chat_ctx.messages[-1]
+    await mem0.add(
+        [{"role": "user", "content": user_msg.content}], 
+        user_id=USER_ID
+    )
+    
+    # Search for relevant memories
+    results = await mem0.search(
+        user_msg.content, 
+        user_id=USER_ID,
+    )
+    
+    # Augment context with retrieved memories
+    if results:
+        memories = ' '.join([result["memory"] for result in results])
+        logger.info(f"Enriching with memory: {memories}")
+        
+        rag_msg = llm.ChatMessage.create(
+            text=f"Relevant Memory: {memories}\n",
+            role="assistant",
+        )
+        
+        # Modify chat context with retrieved memories
+        chat_ctx.messages[-1] = rag_msg
+        chat_ctx.messages.append(user_msg)
+```
+
+This function:
+- Stores user messages in Mem0
+- Performs semantic search for relevant memories
+- Augments the chat context with retrieved memories
+- Enables contextually aware responses
+
+### 3. Prewarm and Entrypoint Functions
+
+```python
+def prewarm_process(proc: JobProcess):
+    # Preload silero VAD in memory to speed up session start
+    proc.userdata["vad"] = silero.VAD.load()
+
+async def entrypoint(ctx: JobContext):
+    # Connect to LiveKit room
+    await ctx.connect(auto_subscribe=AutoSubscribe.AUDIO_ONLY)
+    
+    # Wait for participant
+    participant = await ctx.wait_for_participant()
+    
+    # Initialize Mem0 client
+    mem0 = AsyncMemoryClient()
+
+    # Define initial system context
+    initial_ctx = llm.ChatContext().append(
+        role="system",
+        text=(
+            """
+            You are a helpful voice assistant.
+            You are a travel guide named George and will help the user to plan a travel trip of their dreams. 
+            You should help the user plan for various adventures like work retreats, family vacations or solo backpacking trips. 
+            You should be careful to not suggest anything that would be dangerous, illegal or inappropriate.
+            You can remember past interactions and use them to inform your answers.
+            Use semantic memory retrieval to provide contextually relevant responses. 
+            """
+        ),
+    )
+
+    # Create VoicePipelineAgent with memory capabilities
+    agent = VoicePipelineAgent(
+        chat_ctx=initial_ctx,
+        vad=silero.VAD.load(),
+        stt=deepgram.STT(),
+        llm=openai.LLM(model="gpt-4o-mini"),
+        tts=openai.TTS(),
+        before_llm_cb=_enrich_with_memory,
+    )
+
+    # Start agent and initial greeting
+    agent.start(ctx.room, participant)
+    await agent.say(
+        "Hello! I'm George. Can I help you plan an upcoming trip? ",
+        allow_interruptions=True
+    )
+
+# Run the application
+if __name__ == "__main__":
+    cli.run_app(WorkerOptions(entrypoint_fnc=entrypoint, prewarm_fnc=prewarm_process))
+```
+
+The entrypoint function:
+- Connects to LiveKit room
+- Initializes Mem0 memory client
+- Sets up initial system context
+- Creates a VoicePipelineAgent with memory enrichment
+- Starts the agent with an initial greeting
+
+## Create a Memory-Enabled Voice Agent

+
+## Key Features of This Implementation
+
+1. **Semantic Memory Retrieval**: Uses Mem0 to store and retrieve contextually relevant memories
+2. **Voice Interaction**: Leverages LiveKit for voice communication
+3. **Intelligent Context Management**: Augments conversations with past interactions
+4. **Travel Planning Specialization**: Focused on creating a helpful travel guide assistant
+
+## Running the Example
+
+To run this example:
+
+1. Install all required dependencies
+2. Set up your `.env` file with the necessary API keys
+3. Ensure your microphone and audio setup are configured
+4. Run the script with Python 3.11 or newer and with the following command:
+```sh
+python mem0-livekit-voice-agent.py start
+```
+5. After the script starts, you can interact with the voice agent using [Livekit's Agent Platform](https://agents-playground.livekit.io/) and Connect to the agent inorder to start conversations. 
+
+## Best Practices for Voice Agents with Memory
+
+1. **Context Preservation**: Store enough context with each memory for effective retrieval
+2. **Privacy Considerations**: Implement secure memory management
+3. **Relevant Memory Filtering**: Use semantic search to retrieve only the most pertinent memories
+4. **Error Handling**: Implement robust error handling for memory operations
+
+## Debugging Function Tools
+
+- To run the script in debug mode simply start the assistant with `dev` mode:
+```sh
+python mem0-livekit-voice-agent.py dev
+```
+
+- When working with memory-enabled voice agents, use Python's `logging` module for effective debugging:
+
+```python
+import logging
+

+### History Store
+
+Mem0 TypeScript SDK support history stores to run on a serverless environment:
+
+We recommend using `Supabase` as a history store for serverless environments or disable history store to run on a serverless environment.
+
+<CodeGroup>
+```typescript Supabase
+import { Memory } from 'mem0ai/oss';
+
+const memory = new Memory({
+  historyStore: {
+    provider: 'supabase',
+    config: {
+      supabaseUrl: process.env.SUPABASE_URL || '',
+      supabaseKey: process.env.SUPABASE_KEY || '',
+      tableName: 'memory_history',
+    },
+  },
+});
+```
+
+```typescript Disable History
+import { Memory } from 'mem0ai/oss';
+
+const memory = new Memory({
+  disableHistory: true,
+});
+```
+</CodeGroup>
+
+Mem0 uses SQLite as a default history store.
+
+#### Create Memory History Table in Supabase
+
+You may need to create a memory history table in Supabase to store the history of memories. Use the following SQL command in `SQL Editor` on the Supabase project dashboard to create a memory history table:
+
+```sql
+create table memory_history (
+  id text primary key,
+  memory_id text not null,
+  previous_value text,
+  new_value text,
+  action text not null,
+  created_at timestamp with time zone default timezone('utc', now()),
+  updated_at timestamp with time zone,
+  is_deleted integer default 0
+);
+```
