Bug Report

Hi guys,

I'm using version 0.5.12. I've tried using Kokoro JS to no avail.

This has been tried on a M2 MacBookPro with 16 Gb RAM.

When a user (admin or regular) enables Kokoro JS and chooses a voice, the browser downloads the model and loads it. At this point CPU is at 100% and Safari hangs and reloads automatically the web page. Chrome, on the other hand, handles well the loading of the model, it does not hang.

Anyway, Kokoro JS does no seem ever to be used. Whenever I try to read aloud a response or "call" the model, all I get is the audio that has been configured using the "Admin Settings", and not the "User settings". "Admin settings" does not allow Kokoro JS to be selected, only APIs or Transformers (local).

Maybe I'm doing something wrong...

Thanks,

Aleix.
