Driver App: voice announcement settings
Last updated 2026-10-15
Turn announcements on/off, pick all or critical-only mode, adjust speed and volume, choose a language, and test the voice — all free and offline.
Voice announcements use the phone's built-in text-to-speech — zero cost and it works offline (tunnels, mountains, no signal). Open More → Voice announcements to configure. The phone speaks navigation turns, new assignments, time-window and HOS warnings, and dispatcher messages so your eyes stay on the road.
Master switch and mode#
- Master switch: turns all voice announcements on or off.
- All: every announcement. Critical only: only urgent (red) and important (yellow) ones — the default, to avoid noise. Mute: no voice, banners only.
Speed, volume, language#
- Speed: 0.5x–2.0x slider, default 1.0x.
- Volume: 0–100, independent of media volume. Between 22:00 and 06:00 the volume drops 30% automatically.
- Language: Follow app (default) or pick one of the six languages manually.
External navigation and categories#
- Use external navigation: turn-by-turn goes to Google/Apple/Waze; this app then only announces business items (assignments, warnings, dispatch messages).
- Category switches: navigation / tasks / warnings / dispatch — turn a whole group on or off. Expand "per-scenario switches" to control each of the 19 announcements individually.
Test and first-time unlock#
Tap the Test button (🔊) to hear a sample with your current settings. On iPhones, the browser requires one tap before any voice can play — the Test button (or any check-in button) performs that unlock, so tap it once when you start your shift.
Settings are saved on the phone instantly and work offline — they don't need a signal to take effect.
