I want to implement a session restart method in my agent.py I want to use a new session. this is my current implementation: await session.aclose() await session.start() how can i implement a session restart by using a new session

Thanks for reaching out, Ahmed. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

the problem im facing is that whenever i restart a session, i lose access to the agents transcription in my Frontend. how do i resolved this?

Hey there! To keep your agent transcription access working smoothly in the frontend even after restarting a session, here’s a friendly step-by-step guide: Frontend Integration 1. Set Up Event Listeners: Use the LiveKit SDK to listen for

RoomEvent.TranscriptionReceived

in your frontend. This way, you’ll catch each transcription segment as it comes in. Each segment has a unique ID and tells you if it’s final.

useEffect(() => {
    if (!room) {
        return;
    }
    
    const handleTranscriptionReceived = (transcriptionSegment) => {
        // Here’s where you handle the transcription segment
        // You can check if the segment is final to know when it’s done
    };

    room.on(RoomEvent.TranscriptionReceived, handleTranscriptionReceived);

    return () => {
        room.off(RoomEvent.TranscriptionReceived, handleTranscriptionReceived);
    };
}, [room]);

2. Keep Transcriptions Across Sessions: To make sure your transcription data sticks around even if the session restarts, store it in a state management tool like React Context or Redux.

const [transcriptions, setTranscriptions] = useState<{ [id: string]: TranscriptionSegment }>({});

// Inside handleTranscriptionReceived
setTranscriptions(prev => ({
    ...prev,
    [transcriptionSegment.id]: transcriptionSegment
}));

Agent Configuration 1. Turn On Transcription Forwarding: Double-check that your

AgentSession

is set up to forward transcriptions. Usually, this means enabling transcription in the

RoomOutputOptions

when you start the session.

session.start(
    agent=your_agent,
    room=ctx.room,
    room_output_options=RoomOutputOptions(
        transcription_enabled=True
    )
)

2. Handle Session Restarts Gracefully: When you restart a session, make sure transcription forwarding gets set up again properly. This might mean reapplying the

room_output_options

or confirming your agent’s transcription settings stay intact. By following these steps, you’ll keep those transcriptions flowing in the frontend, no matter how many times the session restarts. If you want me to walk you through any part or need some examples, just give me a shout!

i think the trackid of the agent changes hence im unable to access the transcripts. this is how im accessing transcripts: const voiceAssistant = useVoiceAssistant();

Hey there! If you’re looking to handle changing track IDs for agent transcripts in your frontend, here’s a friendly step-by-step guide to help you out: 1. Set Up Transcription Event Listening: Start by using the

RoomEvent.TranscriptionReceived

event to catch transcription updates. This event gives you

TranscriptionSegment

objects, which include the transcript text, segment ID, and whether the segment is final or not. 2. Implement State Management for Transcriptions: Keep a state map (like a dictionary) where each key is a segment ID, and the value is the corresponding

TranscriptionSegment

. Update this state whenever you get a new transcription segment. 3. Handle Segment Updates: • Check if each incoming segment already exists in your state map. • If it does and it’s marked as

final

, go ahead and replace the old entry. • If it’s not final yet, update the entry with the latest segment data. 4. Display the Transcriptions: Once a segment is marked as final, show the full transcription. Use the participant and track info from the transcription event to make sure the transcription is correctly attributed. Here’s an example implementation to get you started:

import { useEffect, useState } from "react";
import {
  RoomEvent,
  TranscriptionSegment,
  Participant,
  TrackPublication,
} from "livekit-client";
import { useMaybeRoomContext } from "@livekit/components-react";

export default function AgentTranscriptions() {
  const room = useMaybeRoomContext();
  const [transcriptions, setTranscriptions] = useState<{ [id: string]: TranscriptionSegment }>({});

  useEffect(() => {
    if (!room) {
      return;
    }

    const updateTranscriptions = (
      segments: TranscriptionSegment[],
      participant?: Participant,
      publication?: TrackPublication
    ) => {
      setTranscriptions((prev) => {
        const newTranscriptions = { ...prev };
        for (const segment of segments) {
          newTranscriptions[segment.id] = segment;
        }
        return newTranscriptions;
      });
    };

    room.on(RoomEvent.TranscriptionReceived, updateTranscriptions);
    return () => {
      room.off(RoomEvent.TranscriptionReceived, updateTranscriptions);
    };
  }, [room]);

  return (
    <div>
      <h2>Agent Transcriptions</h2>
      {Object.values(transcriptions).map((segment) => (
        <div key="{segment.id}">
          <p>
            <strong>
              {segment.participant?.identity || "Unknown"}:{" "}
            </strong>
            {segment.text}
          </p>
        </div>
      ))}
    </div>
  );
}

Some quick tips to keep in mind: • Track Changes: Since track IDs can change, lean on the `TranscriptionSegment`’s

id

and

participant

fields to uniquely identify and attribute each transcription. • Final Segments: Only show transcriptions when they’re marked as

final

so you’re sure you have the full text. • Participant Info: Always include participant details to keep context clear, especially if multiple people are involved. This way, you’ll smoothly handle changing track IDs and keep your transcription display accurate and reliable.
