To ensure the last speech is played before ending a call when using ElevenLabs TTS, you can use the

wait_for_playout()

method on the

SpeechHandle

. Here’s how: • Generate Speech and Get Handle: Use

session.say()

or

session.generate_reply()

to create a

SpeechHandle

object. Set

allow_interruptions=False

to prevent interruptions during the speech. • Wait for Speech Playout: Call

await handle.wait_for_playout()

to ensure the speech finishes before proceeding. This method blocks until the speech has completed playing. • End the Call: After the speech completes, end the call using the

delete_room

API. This ensures the session terminates only after the last speech is played. Here’s an example:

handle = session.say("Thank you for calling. Goodbye!", allow_interruptions=False)
await handle.wait_for_playout()
await ctx.api.room.delete_room(api.DeleteRoomRequest(room=ctx.room.name))

Alternatively, if you prefer using

asyncio.sleep()

, you can poll the speech handle’s

done()

status:

handle = session.say("Goodbye message...", allow_interruptions=False)

while not handle.done():
    await asyncio.sleep(0.1)

await ctx.api.room.delete_room(api.DeleteRoomRequest(room=ctx.room.name))

Using

wait_for_playout()

is recommended as it handles the playout asynchronously without busy waiting. Let me know if you need further assistance!
