Incorrect transcription on failing audio capture

[IngLP]

Hi,
I want to report that when this error occurs: #863 , the WHOLE audio transcription is committed as agent speech, but NONE of that speech has been said:

2024-12-18 21:52:43,520 DEBUG livekit.agents.pipeline: speech playout started

2024-12-18 21:52:43,543 DEBUG livekit.agents.pipeline: committed agent speech

I can live with that issue occurring sometimes, but the agent should be aware that no speech has been produced. This is causing huge problems in user interaction.

Any help?
