| # | Input | Expected behavior | Check |
|---|---|---|---|
| 01 | User starts speaking while the assistant is still playing audio_output. The server emits a user_interruption event. | On user_interruption, immediately stop local playback of the assistant's audio_output and stop enqueuing further chunks for that turn, then yield to the user. Treat the interrupted assistant turn as cut short, not completed. | Pass / FailAi Platformcritical |
| 02 | The client has pre-buffered several seconds of assistant audio_output for smooth playback when the user barges in. | Flush the pre-buffered assistant audio on interruption so the assistant does not continue speaking from a stale buffer. Reconcile the displayed transcript with what was actually heard (truncate at the interruption point). | Pass / FailAi Platformhigh |
| 03 | The user pauses briefly mid-sentence to think; a naive client treats the first silence as end-of-turn and the assistant interrupts the user. | Rely on EVI's prosody-aware end-of-turn signaling rather than a fixed client-side silence timer; let the server decide turn boundaries from VAD + prosody. Do not force a response on the first short pause. | Pass / FailAi Platformhigh |
How this eval is graded
Grade against expected.ideal_behavior and expected.rubric. Per-criterion pass requires mean >= 4.0 and no criterion below 3. Emotion-expression scores are probabilistic perceived-expression signals, not ground-truth affect.
