Dessa: the most authentic full-duplex speech model ever built

Dessa is a full-duplex speech AI model trained exclusively on human conversation audio that can engage in realistic real-time dialogue with natural emotion, timing, and nuance. Unlike current voice AI systems that convert speech to text and lose information, Dessa processes sound directly and generates responses with authentic human-like qualities such as mid-sentence laughter, appropriate interruptions, and dynamic vocal expression. The model represents a new category of AI interaction where conversation flows naturally without pre-trained models or text intermediaries.
