MetaVoice is building AI for voice conversations that feels just like talking to a human.
Voice AI today cannot hold real conversations. It requires walkie-talkie style turns, lacks empathy and has an inconsistent personality.
Developers are unable to build long-form experiences out of the box and users disengage. This limits voice AI to simple receptionist tasks and basic customer support, blocking high-value use cases (therapy, coaching, sales) where fluid dialogue and emotional intelligence matter most.
Scaling current tech will not solve this.
Our solution is a duplex speech-to-speech AI for developers, designed to feel just like talking to a human.
