Undefined error on Inference API (serverless) for several HF text-to-speech tasks

I tried several TTS models on the HF web (by typing my text below “Inference API” on the right side of the HF page). Here are several examples, including my own:

All error messages are the same: Undefined (see attached). Does anyone know how to solve this issue?

I have checked the call it gives the internal server error.

I am also encountering an “Internal Server Error” while trying to use the Inference API for both my own fine-tuned Speech T5 model and the original Microsoft Speech T5 model. This issue persists across different environments, including Google Colab and Visual Studio Code.

I have opened a discussion on Hugging Face’s forum here: microsoft/speecht5_tts · Internal Server Error while using Inference API for Speech T5

If anyone has experienced similar issues or has a possible solution, please share!

Also experiencing this same issue with every TTS model I’ve tried on the serverless inference API.

The Serverless Inference API is currently turned off for most models. This is probably because the shared resources on the server have been exhausted. It is turned on for microsoft/speecht5_tts, but it does not actually work because the configuration settings are not properly set in README.md or json.
It is better to load it locally or in Spaces and use it.
