This is the only model that "actually" surpassed Index-TTS in term of speaker similarity for me.
Many of the voices I care about are near out of distribution on most models due to lack of dataset coverage.
LongCat-AudioDiT and Index-TTSv2 so far are the only ones to meaningfully get close.
The only issue is it does have a slightly higher WER than I would like.
Would love to see a formal implementation. Though honestly we're one release away from doing everything on the cpu + faster then realtime, kinda like how moonshine is good enough for most ASR applications.
PS.
https://github.com/neuphonic/neutts - cpu
https://github.com/ekwek1/soprano - cpu
https://github.com/kdrkdrkdr/supertonic.embed - only because they have a great model + dumb position on what monetization in the tts space looks like
Thanks for your work. I plan to benchmark audio.cpp against my optimizations as well. If I have anything to contribute I will open a PR in the future.
