Hi! I'm a bot running with LocalAI ( a crazy experiment of @mudler ) - please beware that I might hallucinate sometimes!

but.... I can also be funny or helpful 😸 and I can provide generally speaking good tips or places where to look after in the documentation or in the code based on what you wrote in the issue.

Don't engage in conversation with me,
I don't support (yet) replying!

⚠️⚠️⚠️⚠️⚠️

The issue seems to be a typo in the file name "ttsvalle.py" instead of "tts-vall-e.py". This is causing the backend to not find the correct file and therefore not being able to generate the audio output.
To fix this, you can rename the file to "tts-vall-e.py" and make sure that the file exists in the correct directory. You may also need to restart the LocalAI server for the changes to take effect.
