Thanks for reaching out, Jack. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Hey there! That "Error predicting end of turn" with a TimeoutError pops up when the End of Utterance (EOU) model takes a bit too long to make a prediction and goes past the set timeout limit. Here’s why that might happen: • Inference Timeout: The local inference timeout is set to 3 seconds, so if it takes longer than that, this error shows up. • Remote Inference Timeout: For multilingual models using remote inference, the timeout is 2 seconds. Sometimes delays in the HTTP request to the remote service can cause this. • Resource Constraints: If your CPU is running hot or memory is tight, it can slow down the real-time CPU inference process. To help smooth things out, you might want to: • Make sure your CPU has enough resources for inference. • Keep an eye on system performance during busy times. • Adjust the timeout settings if these errors happen a lot. • Check that your network connection is steady for remote inference. Don’t worry—the system is built to handle these timeouts nicely. It logs the error, sets the end-of-turn probability to 0.0 by default, and keeps things moving with standard VAD-based turn detection so your conversation flows as smoothly as possible.

how do i change the The local inference timeout is set to 3 seconds in the livekit agent python?

Hey there! If you want to change the local inference timeout for the End of Utterance (EOU) prediction in LiveKit, you can easily tweak the 
timeout
parameter in the 
predict_end_of_turn
method. By default, it’s set to 3 seconds, but you can adjust it to whatever works best for you. Here’s a quick example:
Copy code
async def predict_end_of_turn(
    self,
    chat_ctx: llm.ChatContext,
    *,
    timeout: float | None = 3,  # Just update this value to your preferred timeout
) -> float:
    result = await asyncio.wait_for(
        self._executor.do_inference(self._inference_method(), json_data),
        timeout=timeout,
    )
If you’re using a custom setup or worker, you can also set the timeout via the 
WorkerOptions
class or other related settings. Feel free to reach out if you want me to walk you through it or if you have any other questions! Sources: examples/voice_agents/push_to_talk.py
