MetaVoice focuses on duplex speech technology that enables voice conversations with AI to feel familiar, natural, and emotionally aware. It centers on a single speech‑to‑speech model that listens and speaks at the same time, so phone interactions can handle interruptions, overlapping speech, and background noise without rigid turn‑taking. The product is positioned around live revenue calls, with infrastructure and controls intended for real production environments rather than content generation. MetaVoice emphasizes human‑like, emotive speech and low latency responses, aiming to preserve the emotional tone of the speaker while transforming or generating voice. Its messaging highlights end‑to‑end speech handling and real‑time capabilities as key differentiators in the voice AI space.it is an AI voice technology platform focused on realistic text-to-speech, voice cloning, and conversational voice experiences. Its technology includes expressive speech synthesis and the open-source MetaVoice-1B model, designed for generating natural-sounding English speech.
