A voice bot demo usually starts with permission already granted, a quiet room, a stable network, and the app in the foreground. Mobile users get phone calls, Bluetooth switches, revoked permissions, process death, and tunnels.
Voice correctness is a lifecycle contract.
device: Pixel 9

Record speech-recognition mode, voice provider/model version, whether audio leaves the device, and retention policy. Without these, latency and privacy observations cannot be reproduced.
| Starting state | Event | Expected outcome |
|---|---|---|
| recording | permission revoked | stop capture, discard or preserve per visible policy, explain recovery |
| recording | incoming call | release audio focus, preserve draft safely |
| up | network lost | show bounded retry or explicit failure; no duplicate request |
| speaking | Bluetooth disconnects | or switch route visibly; never blast private audio unexpectedly |
| backgrounded | OS kills process | recover authoritative task state without replaying submission |
| processing | user cancels | stop playback and mark server cancellation state separately |
Measure permission-to-record time, end-of-speech to transcript, transcript to first response, total completion, uploaded bytes, retry count, and battery/thermal state. Report medians and tail latency across repeated runs, not the best attempt.
Privacy copy should answer what is recorded, where it is processed, how long audio and transcripts remain, who can access them, and how deletion works. Permission denial must leave a usable text path. Do not repeatedly prompt users who declined.
Test with VoiceOver or TalkBack, large text, hearing devices where available, noisy rooms, accents represented in your target population, silence, accidental activation, and a user correcting the transcript before submission.
The public MonkeyCode repository documents native mobile support and server-side AI task execution. Voice could be one input mode for that category, but this protocol was not run against MonkeyCode and does not claim a voice feature.
Disclosure: I contribute to the MonkeyCode project. Product context comes from public documentation; no device benchmark or voice integration is claimed.
The happy path proves audio can move. Permission-loss and lifecycle tests prove the feature can be trusted on a phone.
