Real-time speed built for live voice agents

Conversational AI agents are only as good as their ability to respond instantly. Delays break the flow, frustrate users, and reduce trust. Deepgram’s streaming architecture delivers sub-second round-trip latency across speech-to-text and text-to-speech, keeping your voice agents natural, responsive, and humanlike even at scale.
