KhanomTan TTS TTS

An open, commercially-licensed Thai-first text-to-speech model with multiple speaker voices.

KhanomTan TTS was built by Thai NLP contributor Wannaphong Phatthiyaphaibun on top of the YourTTS multilingual VITS architecture, and trained on CC0 and other permissively-licensed Thai corpora including TSync. Where most open TTS models only cover Thai under research-only or non-commercial terms, KhanomTan ships under Apache 2.0, making it a rare commercially-safe choice for the language. It offers a small roster of speaker voices and runs fast at roughly five seconds per generation in around 2GB of VRAM. It fits Thai voiceovers, narration for Thai-language apps, and accessibility tooling where licensing clarity matters.
