how to livekit with langflow using VoicePipelineAgent ?

It seems likely that integrating LiveKit with Langflow using the

VoicePipelineAgent

involves setting up a voice pipeline that processes audio input and generates responses using a sequence of models: Speech-to-Text (STT), a Language Model (LLM), and Text-to-Speech (TTS). To achieve this, you would typically configure the

VoicePipelineAgent

with the desired models and parameters. For example, you might use Deepgram for STT, OpenAI for LLM, and Cartesia for TTS, as suggested in the LiveKit documentation. You would also need to ensure that your Langflow setup can interface with these models, possibly by using plugins or APIs that allow for such integration. Would you like more detailed guidance on setting up the

VoicePipelineAgent

or integrating it with Langflow? Sources: - VoicePipelineAgent Documentation 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@millions-hair-24956 how to integrating livekit with langflow using VoicePipelineAgent in nodejs ? but I want to change the llm with langflow.

It seems likely that integrating LiveKit with Langflow using the

VoicePipelineAgent

in Node.js involves replacing the default LLM with Langflow's LLM. Here's a general approach: 1. Set Up VoicePipelineAgent: Initialize the

VoicePipelineAgent

with the necessary components like VAD, STT, and TTS. You can use existing plugins for these components. 2. Replace LLM with Langflow: Instead of using the default LLM (e.g., OpenAI), you would need to create a custom LLM plugin or module that interfaces with Langflow. This involves implementing the necessary API calls or logic to connect to Langflow's LLM. 3. Configure the Agent: Pass your custom LLM implementation to the

VoicePipelineAgent

during its setup. Ensure that your custom LLM is compatible with the expected interface used by the agent. 4. Start the Agent: Use the

start

method to begin processing audio input and generating responses using your custom LLM. Here's a basic example of how you might set up the

VoicePipelineAgent

in Node.js:

const { VoicePipelineAgent } = require('livekit-agents');
const { VAD, STT, TTS } = require('your-plugins'); // Replace with actual plugins
const { CustomLLM } = require('your-langflow-integration'); // Your custom LLM integration

const agent = new VoicePipelineAgent({
  vad: new VAD(),
  stt: new STT(),
  llm: new CustomLLM(), // Your custom LLM
  tts: new TTS(),
  // Additional configuration options
});

agent.start(room, participant);

@millions-hair-24956 how to create a dynamic llm.functionContext in nodejs ?

To create a dynamic

llm.FunctionContext

in Node.js, you can define a set of functions that your LLM can call during its operation. This involves creating a

FunctionContext

object that contains callable functions, each defined with a description and parameters. Here's a basic example of how you might set up a dynamic

FunctionContext

in Node.js: 1. Define Callable Functions: Create functions that the LLM can call. Each function should have a description and parameters defined. 2. Create FunctionContext: Use these functions to create a

FunctionContext

object. 3. Integrate with LLM: Pass the

FunctionContext

to your LLM instance. Here's a code snippet to illustrate this:

const { FunctionContext } = require('livekit-agents'); // Import FunctionContext

// Define a callable function
const getWeather = {
  description: 'Get the weather for a specific location',
  execute: async (args) => {
    const location = args.location;
    // Logic to get weather for the location
    return `The weather in ${location} is sunny.`;
  },
  parameters: {
    location: { type: 'string', description: 'The location to get the weather for' }
  }
};

// Create a FunctionContext with the defined functions
const functionContext = new FunctionContext({
  getWeather: getWeather
});

// Pass the FunctionContext to your LLM
const llm = new YourCustomLLM({
  fncCtx: functionContext
});

@millions-hair-24956 how to unpublish track agent for all remote participant ?

To unpublish a track for all remote participants in LiveKit, you can use the

unpublishAllTracks

method from the

Participant

class in the LiveKit client SDK. This method will unpublish all tracks for a participant, effectively making them unavailable to all remote participants. Here's a basic example using the LiveKit client SDK in Dart:

import 'package:livekit_client/livekit_client.dart';

Future<void> unpublishAllTracks(Participant participant) async {
  await participant.unpublishAllTracks();
}

This method will unpublish all tracks for the specified participant. If you want to unpublish specific tracks, you can use the

unpublishTrack

method with the track's SID. Would you like more detailed guidance on this process? Sources: - unpublishAllTracks method 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@millions-hair-24956 i want the answer for nodejs

To unpublish a track for all remote participants in LiveKit using Node.js, you can use the

unpublishTrack

method on the

LocalParticipant

object. This method allows you to unpublish a specific track, making it unavailable to all remote participants. Here's a basic example using the LiveKit client SDK in Node.js:

const { Room } = require('livekit-client');

async function unpublishAllTracks(room) {
  const localParticipant = room.localParticipant;
  const tracks = localParticipant.tracks;

  for (const publication of tracks.values()) {
    await localParticipant.unpublishTrack(publication.track);
  }
}

// Example usage
(async () => {
  const room = new Room();
  // Connect to the room and perform other setup tasks
  await unpublishAllTracks(room);
})();

This code iterates over all published tracks of the local participant and unpublishes each one. Make sure to replace the room connection logic with your actual room setup.
