VOICE CUES

Your trainer in your ear. JoyTrain announces interval changes, countdowns, and workout milestones using your browser\u2019s built-in speech synthesis. No microphone access needed — all output.

How it works

· JoyTrain uses the browser\u2019s built-in Web Speech API — no microphone access, no audio upload.
· The first time you start a session, the browser will show a brief audio init; this is required by Chrome / Safari.
· Voice is per-device. To use a different voice on your phone, change the system\u2019s TTS voice in your phone\u2019s accessibility settings.
· Settings are saved to localStorage so they persist across sessions on the same device.
