Hello, we've experienced bugs where some User voice input were not trasncribed at all , therefore the agent was never aware that the user answered or spoke. This happened in CallId: 0199e377-c770-733c-9efc-6410ee208b4f at the 2:02 minute mark. This is not the first time this happens and was wondering what can cause this and how we could fix this, since it greatly affects the user experience. In the recording, we can see the user voice input is really clear, but no transcription reached the LLM model....

To troubleshoot missing user transcriptions, start by reviewing the Call Logs in your Vapi dashboard: 1. Go to

Observe > Call Logs

and locate the affected call (use the CallId and timestamp). 2. Check for any error messages, missing transcript segments, or tool execution issues at the 2:02 mark. 3. If you see gaps or errors, also review the API Logs for authentication or payload problems. This will help you pinpoint whether the issue is with the transcriber, configuration, or an external integration. Tip: Detailed logs often reveal if the problem is model-related or due to a misconfiguration.

@User can someone look at this. I see no errors in logs at that time. No transcription logs either when there should be.

I've also experienced this. In the Vapi UI I can hear the audio of the user speaking but no transcript shows up and in the logs there are no traces of that audio being handled. In this case the user talked fairly quiet but I'd still expect it to be picked up if I can hear it in the audio recording clearly. Call ID 019a73e0-5d33-7bb9-9818-91ec019b2918

@Pat No answer frm @User yet. This seems to be a problem regarding the transcriber. I use Deepgram Nova-3. Even with confidence treshold lowered to 0 it still happens...

Hey sorry for the delayed response. Could you please provide a more recent call id preferably made within the last 7 days?
