g
To troubleshoot the issue of a user not being able to publish a track in a LiveKit room, consider the following steps: 1. Check Permissions: Ensure that the participant's token has the necessary permissions to publish tracks. According to the TrackPublishException class, a common reason for failure is the lack of track publish permission. 2. Network Conditions: Verify that the network conditions are stable, as poor network conditions can also prevent track publishing. 3. Track Already Exists: If the track is already published, attempting to publish it again will throw an exception. Ensure that the track is not already published before attempting to publish it again. 4. Use Default Methods: For simplicity, use methods like
setMicrophoneEnabled
or
setCameraEnabled
to enable tracks, as they handle common cases and permissions automatically (Handling common track types). Would you like more detailed guidance on any of these steps?

It seems like you're trying to set up a MultimodalAgent with LiveKit to handle voice interactions, but you're facing issues with committing audio after the initial welcome message. Here are a few things to check and consider: 1. Audio Track Subscription: Ensure that the audio tracks are being subscribed to correctly. The agent should be able to receive and process audio from the participant. Verify that the participant's audio track is being subscribed to and that the agent is set up to listen for incoming audio. 2. Voice Activity Detection (VAD): Check the VAD settings in your
RealtimeModel
. The
threshold
,
prefix_padding_ms
, and
silence_duration_ms
parameters should be configured to accurately detect when the participant is speaking. Adjust these settings if necessary to improve detection. 3. Event Handling: Make sure that the agent is set up to handle events such as
user_started_speaking
and
user_stopped_speaking
. These events can help manage the flow of conversation and ensure that the agent responds appropriately. 4. Debugging Logs: Enable detailed logging to capture more information about the interaction. This can help identify where the process might be failing. Look for logs related to track subscription, VAD events, and any errors that might occur during the session. 5. Session Management: Ensure that the session is being managed correctly, and that the agent is not prematurely ending the session or missing audio input due to session mismanagement. If you need more detailed guidance on any of these points, please let me know.

@millions-hair-24956 how to do this can you give a code for this
g
To address the issue of committing audio after the initial welcome message, you can ensure that the MultimodalAgent is correctly set up to handle audio input and output. Below is a code snippet that demonstrates how to configure the agent to listen for audio and respond appropriately:
Copy code
from __future__ import annotations

import logging
from dotenv import load_dotenv

from livekit import rtc
from livekit.agents import (
    AutoSubscribe,
    JobContext,
    WorkerOptions,
    cli,
    llm,
)
from livekit.agents.multimodal import MultimodalAgent
from livekit.plugins import openai

load_dotenv(dotenv_path=".env.example")
logger = logging.getLogger("my-worker")
logger.setLevel(logging.INFO)

async def entrypoint(ctx: JobContext):
    logger.info(f"connecting to room {ctx.room.name}")
    await ctx.connect(auto_subscribe=AutoSubscribe.AUDIO_ONLY)

    participant = await ctx.wait_for_participant()

    run_multimodal_agent(ctx, participant)

    logger.info("agent started")

def run_multimodal_agent(ctx: JobContext, participant: rtc.RemoteParticipant):
    logger.info("starting multimodal agent")

    model = openai.realtime.RealtimeModel(
        instructions=(
            "You are a voice assistant created by LiveKit. Your interface with users will be voice. "
            "You should use short and concise responses, and avoiding usage of unpronouncable punctuation. "
            "You were created as a demo to showcase the capabilities of LiveKit's agents framework."
        ),
        voice='shimmer',
        turn_detection=openai.realtime.ServerVadOptions(
            threshold=0.8, prefix_padding_ms=300, silence_duration_ms=200
        ),
        temperature=0.7,
        modalities=["audio", "text"],
    )

    chat_ctx = llm.ChatContext()
    chat_ctx.append(
        text="Context about the user: you are talking to a software engineer who's building voice AI applications."
        "Greet the user with a friendly greeting and ask how you can help them today.",
        role="assistant",
    )

    agent = MultimodalAgent(
        model=model,
        chat_ctx=chat_ctx,
    )
    agent.start(ctx.room, participant)

    # Ensure the agent is listening for audio input
    @agent.on("user_started_speaking")
    async def on_user_started_speaking():
        logger.info("User started speaking")

    @agent.on("user_stopped_speaking")
    async def on_user_stopped_speaking():
        logger.info("User stopped speaking")
        # Process the user's speech and generate a response
        await agent.process_speech()

if __name__ == "__main__":
    cli.run_app(
        WorkerOptions(
            entrypoint_fnc=entrypoint,
        )
    )
Key Points: - Voice Activity Detection (VAD): The
turn_detection
settings are crucial for detecting when the user starts and stops speaking. Adjust these parameters to suit your environment. - Event Handling: The
on_user_started_speaking
and
on_user_stopped_speaking
events are used to manage the conversation flow. - Logging: Use logging to monitor the agent's activity and troubleshoot any issues. This setup should help the agent to listen and respond to user input effectively. If you need further assistance, feel free to ask!
