Spoken Audio Cues
Splits and zones, spoken on-device.

The watch can speak your splits, “one kilometre, five minutes twelve”, along with time milestones, zone crossings, and interval boundaries. Everything is generated on-device, so nothing is sent to a cloud text-to-speech service.
Voices are available in English and German, the cues are fully configurable, and audio ducks like Siri so it respects whatever you’re listening to. It’s off by default, turn it on only if you want it.
