It's difficult to say as there are lots of possibilities, but if you have agent observability enabled, https://docs.livekit.io/deploy/observability/insights/, you can see the audio that the agent heard, which will help isolate where in your pipeline this is happening.

Thank you. I'll see what the agent heard on our future calls. My main suspicions atm are: Using multilingual turn detection on an unsupported language (Arabic) might be cutting the audio at the wrong times. VAD cutting the audio at the wrong times.

Using multilingual turn detection on an unsupported language (Arabic) might be cutting the audio at the wrong times.

I think that's a reasonable supposition, you might want to try disabling the multilingual turn detection and relying on VAD alone
