@millions-hair-24956 How can the function agent.say() be blocking? (e.g if i have another function after, it wait the the speech is finished)

The

agent.say()

function in LiveKit is not inherently blocking, meaning it does not wait for the speech to finish before proceeding to the next function. However, you can achieve a blocking behavior by using the

await

keyword with

agent.say()

, which will ensure that the function waits for the speech to complete before moving on to the next line of code. This is confirmed by the LiveKit documentation, which describes the

say

method as asynchronous. Would you like more details on how to implement this in your code? Sources: - LiveKit documentation 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@millions-hair-24956 i am using await but it is not blocking Here is my code

logger.debug("Redirecting the call...")
        livekit_api = LiveKitAPI()
        print(phrase_de_transfert)
        transfer_to = f'tel:{self.redirection_number}'
        out = await self.assistant.say(phrase_de_transfert)
        await out.wait_for_initialization()
        print(88 * "-")
        # await self.assistant.say("Un instant s'il vous plaît.")
        # await asyncio.sleep(4)
        # Create transfer request
        transfer_request = TransferSIPParticipantRequest(
            participant_identity=self.participant.identity,
            room_name=self.room.name,
            transfer_to=transfer_to,
            play_dialtone=True
        )
        logger.debug(f"Transfer request: {transfer_request.participant_identity}")  # pylint: disable=W1203

        # Transfer caller
        await livekit_api.sip.transfer_sip_participant(transfer_request)
        <http://logger.info|logger.info>(f"Successfully transferred participant {self.participant.identity} to {transfer_to}")  # pylint: disable=W1203

It seems likely that the

await self.assistant.say(phrase_de_transfert)

is not blocking as expected because the

say

method itself does not inherently wait for the speech to finish. According to the LiveKit documentation, the

say

method is asynchronous and returns a

SpeechHandle

, which you can use to manage the speech playback. To ensure that the function blocks until the speech is finished, you should use the

await

keyword with the

join()

method on the

SpeechHandle

returned by

say

. Here's how you can modify your code:

out = await self.assistant.say(phrase_de_transfert)
await out.join()  # Wait for the speech to finish

This should ensure that the code execution waits until the speech is completed before proceeding to the next line. Would you like more detailed guidance on this? Sources: - LiveKit documentation 👍 1 button 👎 0 button 💡 Hint: Mention @millions-hair-24956 in the thread for followups.
