What is voice streaming?
Voice streaming (AgentStream) is the real-time transmission of live voice data during a call to AI engines, supervisors, or external systems.
Unlike static calls, voice streaming enables mid-call intelligence, live transcription, real-time assist, bot actions, multilingual support, and supervisor intervention while conversations are still in progress.
With voice streaming, you can monitor, analyse, automate, and enhance conversations as they happen, not after they end.
