Kitten TTS Demo

Type text, pick a model and a voice, and hear it.

• Kitten TTS 2, KittenML's newest and most expressive model: voices in ten languages (more in preview), emotion tags such as [joyful], sounds such as <laugh> and (((emphasis))). It comes from the KittenML API, so it needs no GPU.
• Kitten TTS 0.8 Mini, Micro and Nano, the open-source models (Apache 2.0). They are loaded when the Space starts and run on its CPU.

The Space needs one secret, set under Settings → Variables and secrets:

• KITTENML_API_KEY: a KittenML API key, used for Kitten TTS 2. The 0.8 models work without it.

The Kitten TTS 2 voice list is read from the API, so new voices appear without a code change. Like the demo on kittenml.com, each visitor gets 4 requests a minute (12 per network) and up to 500 characters per request, and Kitten TTS 2 adds an audio allowance of 5 minutes every six hours (20 per network).

The open-source models are on GitHub and Hugging Face.
