    History, not a live call

    Model output is validated separately. A rejected response is not a failed agent test. Read the recorded date and result for each sample; these are not live calls.

    Measured audio replays

    Whisper → offline reference agent → Kokoro reply · recorded test runs

    4 original synthetic cases

    Fault modes intentionally change the reference agent. File-based processing times include transcription and speech generation; they are not streaming interruption latency. No human participants.

    Original audio samples

    Locally generated Kokoro voices · synthetic, not human recordings

    Change the date

    “Wait, change the booking to Friday. Do not save Thursday.”

    Cancel the booking

    “Cancel that. Do not make any booking.”

    File-based reference-agent replay is measured above. Live microphone streaming and human testing are not validated.
