[erew123]

HI Ooba you said to submit here to get my extension listed.

AllTalk TTS
https://github.com/erew123/alltalk_tts

AllTalk is based on the Coqui TTS engine, similar to the Coqui_tts extension for Text generation webUI, however supports a variety of advanced features.

• Custom Start-up Settings: Adjust your standard start-up settings.
• Nararator: Use different voices for main character and narration.
• Low VRAM mode: Improve generation performance if your VRAM is filled by your LLM. [Screenshot]
• DeepSpeed: When DeepSpeed is installed you can get a 3-4x performance boost generating TTS.
• Local/Custom models: Use any of the XTTSv2 models (API Local and XTTSv2 Local).
• Optional wav file maintenance: Configurable deletion of old output wav files. [Screenshot]
• Documentation: Fully documented with a built in webpage.
• Advanced filtering for cleaner TTS generation: No strange characters slipping through making strange noises.
• Backend model access: Change the models temperature and repetition penalty to tweak how close it stays to the original samples.

Thanks!
