Sound & voice

Voice flag instructions

Action / voice advance notice

Show the upcoming action this far before each signal. Instructions are spoken only when there is enough preparation time; short lead-ins and long announcements are explicitly visual-only. Signal times, the standard lead-in and the 10-second countdown do not change.

Voice 10-second countdown

Countdown voice

Female and male use recordings and share the local horn’s scheduled output clock when available. They never silently switch to device speech. Device voice and Bluetooth relays are best-effort; they cannot guarantee physical sound timing.

Sound horn on this device

After an affected countdown, save the clock readings for diagnosis. The report contains no competitor names or spoken instructions. It does not calibrate or change the audio.

Lead-in before warning signal (5-4-1 / 3-2-1)

With exact-minute starts on, this is the shortest wait before the warning signal.
