IndexTTS
Zero-shot TTS model with high naturalness and speaker similarity.
About
IndexTTS is a zero-shot text-to-speech model that synthesizes speech matching a short reference clip's voice. The IndexTTS2 release adds a method for controlling the duration of generated speech in autoregressive synthesis, which helps tasks like video dubbing that need audio-visual synchronization, alongside emotionally expressive output. It supports multiple languages and runs on a GPU. Released as an open-source model with inference code.
