Speech Synthesis Research Lab

The Next Generation
of Speech Synthesis.

We're building a leaner TTS architecture that achieves competitive naturalness at a fraction of the training data and cost of industry leaders.

Tontaube V0 · Early Research Preview

Hear It For Yourself

Our V0 model, trained on 45,000 hours — less than 1% of industry-standard datasets. Type anything and synthesize speech in real time.
