1. The Psychology of Conversational Latency

Human conversation is fundamentally predictive. When listening to someone speak, our brains anticipate sentence completions and prep vocal cords before the other person stops speaking. Replicating this requires predictive turn detection rather than waiting for complete silence.

3. Streaming STT → LLM → TTS Pipeline

Rather than waiting for the entire transcript, Quto streams partial tokens from deepgram/conformer STT straight to the LLM. As soon as the first clause is emitted by the language model, it is fed into our streaming acoustic TTS synthesizer.

2. Voice Activity Detection (VAD) & Barge-In

Quto runs low-latency silero-based VAD running in 20ms audio frames on the media gateway. When a human speaks while the agent is talking, playback stops within 40ms, preventing the robotic phenomenon of an agent talking over a frustrated user.
