I want to reply the user every time using generate_reply() on every use_turn completed

Thanks for reaching out, Rajadurai. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
You're asking to call
generate_reply()
automatically after every user turn completes. I can help—below are concise options and a quick checklist. Which platform are you using (Python or Node.js)? If you're using Python 1. Override the lifecycle hook
on_user_turn_completed
. 2. Call
await self.session.generate_reply()
inside that method. Example:
Copy code
from livekit.agents import Agent, ChatContext

class MyAgent(Agent):
    async def on_user_turn_completed(self, turn_ctx: ChatContext, new_message):
        await self.session.generate_reply()
If you're using Node.js/TypeScript 1. Override
onUserTurnCompleted
. 2. Call
this.session.generateReply()
inside it. Example:
Copy code
import { voice } from '@livekit/agents';

class MyAgent extends voice.Agent {
  async onUserTurnCompleted(turnCtx, newMessage) {
    this.session.generateReply();
  }
}
Quick checklist and tips • If you need to customize responses, pass
instructions
or context before calling
generate_reply()
/
generateReply()
. • This hook runs when user audio/input ends; use it to guarantee a reply after each user turn. • If you want different behavior for certain turns (silence, short utterances, interruptions), tell me the rules and I’ll show conditional examples. Which language/runtime are you using and do you need examples showing custom instructions or conditional logic?

Does it give two response from agent?

Short answer: No — calling
generate_reply()
from
on_user_turn_completed
will not by itself cause two responses, unless something else also triggers reply generation. Why: • The lifecycle hook runs after the user turn ends; calling
generate_reply()
there produces one reply. • Duplicate replies happen only if another part of your code (another hook, an event listener, or autosend behavior) also calls
generate_reply()
/
generateReply()
for the same turn. How to avoid duplicates: • Ensure only one place calls reply generation for a given turn (commonly the
on_user_turn_completed
hook). • If you have other hooks (e.g.,
on_message_received
, timers, or external events), add a guard/flag or check `turn_ctx`/message IDs to skip additional calls. • For conditional replies, wrap the call:
Copy code
if not turn_ctx.reply_already_sent:
    await self.session.generate_reply()
(or similar logic in Node.js) If you share which other hooks/events you use, I can suggest a concrete guard implementation.
