He was talking about STT models, not TTS. Whisper is open source and a good solution in many cases (in particular finetuned ones).

regarding STT we got also today 2 new models from Nvidia:

second in Open ASR leaderboard https://huggingface.co/spaces/hf-audio/open_asr_leaderboard

Sadly only supports 4 languages (english, german, spanish, french)

In my opinion GPT-SoVITS is the best if you can put in the effort. I'm still using v2 since the output is so good. Its also the best multilingual one in my testing on Japanese inputs.

hadnt messed with that one before. my needs are more real time for voice assistant but was neat to play with on hugginface.

can it support more languages rather than only English, Chinese, Japanese, Korean?
