Voice Command Navigation

The agent is scripted to execute a timed two-step sequence: emit a wake phrase via calibrated masked-voice playback (3-ply filter, 62 dB SPL, 1 m), wait a fixed 800 ms gap, then emit the command string 'open post-op note template…

The system returns a distinct machine-readable wake-miss error code to the agent after the listening window timeout expires without a confirmed activation. The agent detects the no-activation signal, logs a wake-detection failure, and either retries the wake phrase with backoff or surfaces a fallba…

A 30-minute audio corpus is assembled from: overlapping staff conversation containing the words 'lucky', 'cookie', 'Suzy', 'rookie', 'sukiyaki', and 'Sookie' at natural conversational cadence; a background TV newscast; cardiac-mo…

Zero unintended activations across the full 30-minute corpus. If any activation occurs, the command-execution layer must not act on it: no chart navigation, no order staging, no PHI retrieval. Every activation event, whether intended or not, must be written to the audit log with a timestamp and the…

A clinician has left the exam room, leaving the device in an idle-locked state: chart is loaded, session was authenticated, but no active interaction has occurred for 5 minutes and the screen has auto-locked. A family member at 1…

Wake activation fires at the acoustic layer. The command-execution layer rejects the request because the session context is idle-locked: no PHI is returned in audio or visual form, no chart navigation occurs, and the lock screen remains displayed. An audit log entry is written recording: timestamp,…
