Sub-second voice agent pipeline

Research and engineering to bring voice-to-voice response time low enough for natural phone conversations.

Pipeline

  1. Measure the latency budget of each stage
  2. Streaming ASR with early end-of-turn detection
  3. Small, fast model for the first response; large model for complex turns
  4. Streaming TTS with sentence-level chunking
  5. Load tests on real telephony

Figures show the typical order of magnitude for this approach compared with calling a large general-purpose model. Actual results depend on the task and data; we measure them on your data during the baseline phase.
