@FedorRasputin commented on GitHub (Mar 8, 2025):

I have the same issue.
I downloaded the generated file and tried to upload it via Postman, but I got this error: "Cannot extract audio duration. Invalid file or format."
After that, I tried to upload a simple WAV file with audio, and it was successfully recognized.

I use a proxyapi for accessing the OpenAI API, so I can't check this issue on the native OpenAI API.\

UPD

On another API provider, the problem persists as well.

@YuriyGavrilov I'm unable to reproduce this error on my setup. I use local whisper and I've picked a different model, as you can see in my setup below.

Please upload a screenshot of your audio settings, as I think something looks odd with the error you received:

400 Client Error: Bad Request for url: https://XXXXXXXXXX/openai/v1/audio/transcriptions

@FedorRasputin Please post the stack trace from the console for your error.

@michaelmarziani commented on GitHub (Mar 13, 2025):

Hi @FedorRasputin, the way I read this, the error is here:

openwebui-1 | requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://api.proxyapi.ru/openai/v1/audio/transcriptions

A bad request in this context means that the server is rejecting this transcription request. Unfortunately there isn't enough detail in the error message to know why.

To troubleshoot, I would try different servers in my configuration. If this works, then you know it's a problem with this specific server, if you test a few servers and none of them work, either they all are having an issue or there might be a problem in the request code in OWUI.

Good luck!
