Sub-90ms latency, 40+ languages, one API
The generator above runs on Sonic, Cartesia's real-time speech model. It starts streaming audio in well under a second, with sub-90ms model latency, reads in more than 40 languages, and lets you shape pace and emotion. You can clone a voice from a short sample, and call the same model from our API and SDKs.
