Perguntas frequentes

Who maintains index-tts?

index-tts is maintained by the index-tts organization/account on GitHub, together with open-source contributors, in the public repository index-tts/index-tts.

Is index-tts free to use?

Yes — the code is open source under the NOASSERTION license. Check the repository's LICENSE file for the exact terms before commercial use.

Does index-tts need a paid API key?

No API key — models are downloadable and run locally; you need a suitable GPU for reasonable speed, and rights to any voice you clone.
