How can We implement speech to text of all participant in room without agent speaking in existing room?
g
It seems likely that implementing speech-to-text (STT) for all participants in a room without the agent speaking can be achieved by using LiveKit's Agents framework. According to the LiveKit Agents Overview, you can create an agent specifically for transcription purposes. This agent can join the room and perform real-time transcription of audio tracks without needing to respond or speak. To achieve this, you would need to set up an STT agent that subscribes to the audio tracks of all participants in the room. The agent can then process these tracks to generate transcriptions. You can refer to the speech-to-text example provided by LiveKit for guidance on setting up such an agent. Would you like more detailed steps on setting up the STT agent?

For server side can We use cloudflare worker?
@millions-hair-24956 For server side can We use cloudflare worker?
g
It seems likely that using Cloudflare Workers for server-side operations with LiveKit might not be ideal. According to a Slack discussion, LiveKit's SDKs use a NodeJS binary addon for WebRTC signaling, which Cloudflare Workers cannot run due to their limitations with binary execution. This suggests that Cloudflare Workers may not support the necessary functionality for running LiveKit agents or handling WebRTC signaling. Would you like more information on alternative server-side hosting options for LiveKit?

@millions-hair-24956 Give Me code for joining agent to room for speech to text of all participants in room without having the audio of agent in express js
g
It seems likely that to join an agent to a room for speech-to-text (STT) of all participants without the agent's audio being included, you can use the LiveKit Agents framework. Below is a basic example of how you might set up an agent in an Express.js environment to join a room and perform STT on participant audio tracks.
Copy code
const express = require('express');
const { Worker } = require('@livekit/agents');
const { STT } = require('@livekit/agents-plugin-deepgram');

const app = express();
const port = 3000;

// Configure your LiveKit server details
const LIVEKIT_URL = 'your_livekit_url';
const LIVEKIT_API_KEY = 'your_api_key';
const LIVEKIT_API_SECRET = 'your_api_secret';

// Create a new worker
const worker = new Worker({
  url: LIVEKIT_URL,
  apiKey: LIVEKIT_API_KEY,
  apiSecret: LIVEKIT_API_SECRET,
});

// Define the agent
worker.defineAgent('stt-agent', async (agent) => {
  // Use the Deepgram STT plugin
  const stt = new STT({ apiKey: 'your_deepgram_api_key' });

  // Subscribe to all audio tracks in the room
  agent.on('trackSubscribed', async (track) => {
    if (track.kind === 'audio') {
      const transcription = await stt.transcribe(track);
      console.log('Transcription:', transcription);
    }
  });
});

// Start the worker
worker.start();

app.listen(port, () => {
  console.log(`Express server running on port ${port}`);
});
This code sets up an Express.js server and a LiveKit agent using the Deepgram STT plugin. The agent subscribes to all audio tracks in the room and performs transcription. Note that you need to replace placeholders like
your_livekit_url
,
your_api_key
,
your_api_secret
, and
your_deepgram_api_key
with your actual credentials. Would you like more detailed guidance on setting up this environment? Sources: - https://livekit-users.slack.com/archives/C048FRL1N2C/p1728484288.395119 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@millions-hair-24956 How to get bandwith used by room?
g
To get the bandwidth used by a room in LiveKit, you can utilize the Analytics API. This API allows you to list session details, including bandwidth information. Here's a basic example of how you can retrieve bandwidth data for a specific session using Node.js:
Copy code
const fetch = require('node-fetch');

async function getRoomBandwidth(projectId, sessionId, token) {
  const endpoint = `https://cloud-api.livekit.io/api/project/${projectId}/sessions/${sessionId}`;
  try {
    const response = await fetch(endpoint, {
      method: 'GET',
      headers: {
        Authorization: `Bearer ${token}`,
        'Content-Type': 'application/json',
      },
    });
    if (!response.ok) throw new Error('Network response was not ok');
    const data = await response.json();
    console.log('Bandwidth In:', data.bandwidthIn);
    console.log('Bandwidth Out:', data.bandwidthOut);
  } catch (error) {
    console.error('There was a problem:', error.message);
  }
}

// Example usage
const projectId = 'your_project_id';
const sessionId = 'your_session_id';
const token = 'your_access_token';
getRoomBandwidth(projectId, sessionId, token);
This script fetches session details, including
bandwidthIn
and
bandwidthOut
, which represent the bytes of bandwidth uploaded and downloaded, respectively. Ensure you replace
your_project_id
,
your_session_id
, and
your_access_token
with your actual project ID, session ID, and access token. Would you like more detailed instructions on generating the access token or any other part of the process? Sources: - Analytics API 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

THis api is not giving badwidth out
@millions-hair-24956 THis api is not giving badwidth out is there any other api or other way?
g
If the Analytics API is not providing the
bandwidthOut
data, it might be due to the JSON package used by LiveKit, which excludes fields with no value or zero, as discussed in a Slack conversation. This could mean that the bandwidth data is not being recorded or is below a certain threshold. To address this, you can try the following: 1. Verify Session Data: Ensure that the session in question has significant data transfer. Sessions with minimal data might not report bandwidth usage. 2. Use LiveKit Stats API: If available, the LiveKit Stats API might provide more detailed information about bandwidth usage. However, this API is not explicitly documented in the provided sources. 3. Contact Support: If the issue persists, consider reaching out to LiveKit support for assistance. They might provide insights or solutions specific to your setup.

@millions-hair-24956 HOw to get session id of active room for getting bandwidth it should not give non-active session id of room
g
It seems likely that to get the session ID of an active room, you can use the LiveKit Analytics API to list sessions and filter for active ones. However, the API does not directly provide a way to filter only active sessions by room name. You would need to manually filter the results based on the session's
lastActive
timestamp or
numActiveParticipants
. Here's a basic approach using Node.js to list sessions and filter for active ones:
Copy code
const fetch = require('node-fetch');

async function getActiveSessionId(projectId, roomName, token) {
  const endpoint = `https://cloud-api.livekit.io/api/project/${projectId}/sessions`;
  try {
    const response = await fetch(endpoint, {
      method: 'GET',
      headers: {
        Authorization: `Bearer ${token}`,
        'Content-Type': 'application/json',
      },
    });
    if (!response.ok) throw new Error('Network response was not ok');
    const data = await response.json();
    const activeSession = data.sessions.find(session => 
      session.roomName === roomName && session.numActiveParticipants > 0
    );
    if (activeSession) {
      console.log('Active Session ID:', activeSession.sessionId);
      return activeSession.sessionId;
    } else {
      console.log('No active session found for the specified room.');
      return null;
    }
  } catch (error) {
    console.error('There was a problem:', error.message);
  }
}

// Example usage
const projectId = 'your_project_id';
const roomName = 'your_room_name';
const token = 'your_access_token';
getActiveSessionId(projectId, roomName, token);
This script fetches all sessions and filters them to find an active session for the specified room name. Ensure you replace
your_project_id
,
your_room_name
, and
your_access_token
with your actual project ID, room name, and access token. Would you like more detailed guidance on any part of this process? Sources: - Analytics API 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.
