About

Voice-AI company spun out of the Kyutai non-profit AI research lab, building audio language models for real-time speech — a single neural architecture that unifies transcription, generation and dialogue to deliver ultra-low-latency, natural-sounding multilingual conversation (English, French, German, Spanish, Portuguese) as a voice layer for AI applications, with voices generated from a prompt and tunable for accent, pace and pitch.
