Coqui-TTS has a wide range of voices, the fastest probably being the Glow-TTS models (about the speed of Nix-TTS I'd say). They usually don't handle numbers and temperature etc. as well as Nix-TTS (depends on the model).
Mimic-3 by Mycroft is similar in speed and has good quality too.
Yours looking best however only female voice?
For example my these videos have manually fixed subtitles and auto timed by youtube
Can I use them to train my voice? If so can you release a script to do it?
Or can you also release a male voice?
thank you
e.g. few videos of mine
