ModelRefs / Voice Realtime Stack — Architecture Pattern

Voice Realtime Stack — Architecture Pattern

WebRTC-based voice transport with realtime model APIs and interruption-aware turn management. Turn manager handles interruptions and silence.

Overview

WebRTC for low-latency duplex audio paired with realtime LLM APIs that natively accept and emit audio. Turn manager handles interruptions and silence.

When to use it: You need true-realtime voice with sub-300ms perceived latency.

Known failure modes

  • Packet loss — Audio glitches degrade ASR. Mitigation: FEC + jitter buffer tuning.

When not to use it

  • Routing realtime audio through HTTP polling.
