Voice AI latency testing

Latency testing examines the time between caller speech, system processing and the spoken response. Use it alongside task and outcome checks rather than treating speed alone as a release decision.

Record timestamps for turn start, transcription availability, model response and audio playback. Separate network, provider and application components where the test setup exposes them.

Compare cohorts, line conditions and task types using fixed scenarios. Document assumptions and investigate outliers before changing a release decision.
