AI that learns and interacts like humans
Cartesia is a real-time voice AI platform and API for building conversational AI experiences, serving text-to-speech, speech-to-text, voice cloning/conversion, and hosted voice-agent capabilities powered by Cartesia’s Sonic and Ink models.
Cartesia launched Sonic-3.5 for text-to-speech and Ink-2 for speech-to-text, calling them its new top streaming voice models. The release pairs low-latency voice-agent claims with 42-language support and immediate partner availability.
