Ask HN: Best open-source text-to-speech tools?

2-3 months ago, I asked HN about whether there were any good open source tools or packages for TTS (Text to Speech) [1]

I went through the answers (thank you) and the one I had most success with was tortoise-tts [2], which was seriously impressive, but tediously slow due to leveraging both an autoregressive decoder and a diffusion decoder afaik.

Given the ever increasing rate of change in the space of generative AI, I feel it's worth re-asking the question: what (ideally open source, but it's not necessarily a deal breaker) TTS tools are you having the most success with?
