Turn Detection and Interruptions

Turn Detection

Detects when the caller starts and stops speaking, so the agent knows when to respond. This setting is per language.

Turn Detection Model: the model that predicts the end of a turn, for example Echo Large.

Speech Language: shown when the model supports multiple languages.

Expand Response Timing to tune how long the agent waits:

Setting	Range	Default	Effect
Minimum Wait Time	0–2000 ms	200 ms	The shortest pause before the agent may reply.
Maximum Wait Time	0–5000 ms	500 ms	The longest the agent waits before treating the turn as finished.

If the agent cuts callers off mid-thought, raise Maximum Wait Time. If it feels slow to reply, lower Minimum Wait Time.

Interruption Handling

Controls when the caller can interrupt the agent while it is speaking. This setting applies to all languages.

Mode	Behavior
Hybrid (recommended)	Adjusts interruption timing dynamically. This is the default.
VAD Only	Interrupts as soon as speech is detected. Balanced responsiveness. Turns on VAD automatically.
STT Only	Interrupts once transcribed words arrive. Predictable timing.

Setting	Range	Default
Minimum Interruption Duration	0–1000 ms	200 ms
Minimum Words to Interrupt	0–10	1

Raise both values to stop background noise or short words like “okay” from interrupting the agent.

Voice Activity Detection (VAD)

Detects speech and silence in the caller’s audio. This setting applies to all languages.

Setting	Range	Default	Effect
Speech Sensitivity	0–1	0.50	Higher values detect quieter speech, but noise may also count as speech.
Minimum Speech Duration	0–1 s	0.05 s	Sounds shorter than this are ignored.
Silence Detection Delay	0–3 s	0.40 s	How long silence must last before speech is considered stopped.
