Agent Voice Output interrupted
# support

In this call (callId: c6e70da0-b4ef-4d7b-867e-9ee450788ba7), in two occasion the Agent Stopped talking mid sentence. Once at 2:32 and once at 3:08. Looking at the log, the 2 interruption happened at the same moment as a log like this: 18:33:24:515 [CHECKPOINT] User speech possibly stopping Then followed about 20 logs of user speech starting/stopping (see image) Are these logged causing the Interruption? Because there was absolutely no sound from the user on the recording at those moment, complete silence. Where is this user speech signal come from? How to remove it?

To reduce false interruptions when the agent stops mid-sentence, try adjusting your assistant's
stopSpeakingPlan
to make it less sensitive to brief or accidental triggers. For example:
Copy code
json
"stopSpeakingPlan": {
  "numWords": 2,
  "voiceSeconds": 0.5,
  "backoffSeconds": 1
}
This will require the user to say at least 2 words or speak for 0.5 seconds before the agent stops, helping to filter out spurious detections from silence or background noise. You can further tune these values based on your environment and transcriber behavior.

Hey, could you share a few more call IDs with similar issues? When I tried to look into this, it seems like detected user speech and resulted into the clearing voice pipeline. But I want to be sure on this and identify what's causing this. To suggest you some solution, I need a few more call IDs to identify. Does it happen at a particular time frame, or it happens randomly during the call?

Hey ,I have informed my team to investigate your problem, and they will get back to you.
Hey there! Could you modify your start speaking plan behavior change from VAPI smart and pointing plan to LiveKit and pointing plan? Begin by selecting either the normal or aggressive wait function from the dashboard, and then set the wait seconds to 0.4. This adjustment will ensure that the Assistant won't be interrupted during the conversation.  More Details:

Is there a way to not use LiveKit? My agent will need to be multilingual English and French, therefore I cant rely on LiveKit to solve this issue

If this is the case, then I will suggest you use the Transcription endpointing plan. It works for both English and French. You need to define these rules manually and based on your testing, adapt these rules. Sorry, but as of now, there is no alternative to this.
