I know but it was more of a general comment. A really good TTS just isn't around yes in the OSS sphere. I looked at some of the other suggestions here but they have too many quirks. Dia sounds great but messages must have certain lengths etc and it picks a random voice every time. I'd love to have something self hosted that's as good as openai.
