Bug Report

Description

Bug Summary:
Before setting up openedai-speech, I was using the webapi Google UK English Female voice. After I completed the setup for openedai-speech, I was getting these errors

Open webui logs

INFO:     192.168.1.2:0 - "POST /audio/api/v1/speech HTTP/1.1" 400 Bad Request
ERROR:apps.audio.main:400 Client Error: Bad Request for url: http://openedai-speech:8000/v1/audio/speech
Traceback (most recent call last):
  File "/app/backend/apps/audio/main.py", line 219, in speech
    r.raise_for_status()
  File "/usr/local/lib/python3.11/site-packages/requests/models.py", line 1024, in raise_for_status
    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: http://openedai-speech:8000/v1/audio/speech

Openedai-speech logs

INFO:     192.168.80.3:60494 - "POST /v1/audio/speech HTTP/1.1" 400 Bad Request
2024-07-06 21:26:38.527 | INFO     | openedai:openai_statuserror_handler:106 - BadRequestError(message="Error loading voice: Google UK English Female, KeyError: 'Google UK English Female'", code=400, param=voice)

The error message clearly shows that the requested model didn't get reset or overridden by the value chosen in Admin settings. I had to update the voice model from the user (settings button) settings.

I believe the admin settings and settings should be in sync at least for the admin user.

Steps to Reproduce:

  1. configure audio settings using webapi
  2. configure audio settings using any openai-compatible API
  3. Try to play any message and you will get the error

Expected Behavior:
When the engine changed through admin settings, users should have audio settings updated or reset.

Actual Behavior:
The voice model chosen in settings was being used despite it being invalid.

Environment

  • Open WebUI Version: v0.3.7

  • Operating System: Ubuntu 20.04

  • Browser (if applicable): Chrome latest

Reproduction Details

Confirmation:

  • I have read and followed all the instructions provided in the README.md.
  • I am on the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.

Installation Method

Both open webui and openedai-speech were installed through docker.

Also the settings page doesn't display the full list of available voices when a voice is already selected. I have to delete the selected voice for the complete list to show.

It feels more of an autocomplete than a drop down menu

@ahmedsaed commented on GitHub (Jul 7, 2024):

I've noticed a bug related to caching.

To explain it, I need to understand where the voices list in the dropdown menu comes from. Specifically, I'm referring to the list that includes voices like alloy, echo, fable, etc..

I assumed this list was populated with the available voices, but when I added my custom voice to the openedai-speech config, the list did not include the new voice, even after restarting.

Interestingly, I can manually enter the name of the custom voice and it works, except when I try to play a message that has already been played with one of the predefined voices.

To elaborate, I initially used the alloy voice to play a message. After switching to my custom voice, the play button didn't work, despite the logs showing no errors.

This issue only occurs with custom models. If I select another voice from the predefined list, it plays normally.

Playing the custom voice on a new message, however, works without any problems.

I can confirm that this is an issue. I stood up my own container of openedai-speech, and I can exec into Open WebUI's container, and curl to the speech contsainer, and get it to generate audio (so I know the endpoint is reachable from within Open WebUI) but Open WebUI keeps throwing 400 Bad Requests, when I watch open webui's docker logs.

Also has nothing to do with any custom voices - i can't get it to work with the default settings.

It looks like it's passing in some other setting from elsewhere? "Microsoft Zira"?

Oh, huh - I gotta go into my own personal settings also and change it. Odd.

Follow-up, tried a custom - and can't seem to get custom voices to work at all. only the standard ones included in openedai-speech.

Have you noticed the third message a wrote about a potential bug with caching and invalidation?

What exactly is the problem you are facing?

Have you tested the custom voice through a curl command?

If the model is working through other methods then the issue is probably related to the caching

Don't test the custom model on a message that had been played with the standard ones

Finally, for me - its a custom file that just won't work. But I don't know that it's open-web-ui's issue - because when I curl the file, opened-ai-speech generates the mp3, but it's corrupt - so im probably doing something wrong there.

I had the same issue with the corrupt mp3 file. Change it to a .wav file, and it will work.
