This is my end call tool -

Copy code

@function_tool()
    async def end_call(self, ctx: RunContext):
        """Called when the agents has collected all information and is ready to end the call."""
        <http://log.info|log.info>(f"[{self.agent_name}][correlation_id: {self.room_name}]: Ending the call")
        # await ctx.speech_handle.wait_for_playout()
        await self.session.say(text=f"Thanks for checking that for me. Really appreciate your time today. Bye!!")
        await ctx.wait_for_playout()
        await self.hangup()

Can I have wait for playout after session.say?

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

Thanks — I see you're asking whether it's correct to call

ctx.wait_for_playout()

after

session.say()

in your

end_call

tool. Yes — that is appropriate and the right pattern to ensure the farewell is fully played before hanging up. Why this works •

session.say()

initiates speaking and returns a

SpeechHandle

for that utterance. • Calling

ctx.wait_for_playout()

immediately after will wait until the current/last speech audio finishes playout to the participant. • That guarantees the user hears the full goodbye before

await self.hangup()

runs. Optional alternative • You can also capture the handle explicitly and wait on it:

Copy code

handle = await self.session.say(text="Thanks for checking that for me. Really appreciate your time today. Bye!!")
  await handle.wait_for_playout()
  await self.hangup()

This makes it explicit which speech you’re waiting for (useful if multiple speech ops could overlap). Both approaches are valid; use the explicit handle if you want stricter control. Sources: Agent speech and audio | LiveKit Documentation
