LuxTTS: Open-Source Voice Cloning on a 4GB GPU from Three Seconds of Audio

A new open-source text-to-speech model can clone a voice from just three seconds of audio and runs at 150x realtime on consumer hardware — no cloud subscription required.

LuxTTS, a new open-source voice cloning model, can produce 48kHz audio at 150x realtime on hardware as modest as a 4GB GPU, as @hasantoxr highlighted. It needs just three seconds of reference audio to clone a voice, runs on both CPU and GPU, and requires no subscription to a cloud service like ElevenLabs.
