I was wondering if you could add Tortoise TTS? (specifically from https://github.com/JarodMica/ai-voice-cloning ) (I tested it out, and WOW.. it reminds me of the TTS of character.ai (when you do the voicecall option.) ( specifically the ultrafast mode with only 2 steps)

I think there is an old extension to sillytavern, but not sure if it stil works, nor do I think it's optimal. With alltalk(beta) i think it is perfect to be able to switch engines and just use different TTS. (like you did with parler and SoVits and Piper)
(would be cool if you could somehow implement it. (I'm sorry I don't know how to really code. I started learning python a day ago lol. still got a long way to go.)

No pressure though.
