What Is Index TTS?
Index TTS (IndexTTS) is an online AI text-to-speech and zero-shot voice cloning platform that lets you generate natural, expressive speech from text and short reference audio using the IndexTTS model family.
With Index TTS, you can enter text, upload an authorized reference voice, and generate new speech that follows the voice characteristics of the reference recording. You can preview the result, update your script, and regenerate audio as needed.
The Index TTS model family includes multiple generations with different capabilities for speech quality, expression, timing, language support, and voice control. Explore each model to find the workflow that best fits your project.
