No inspection voice sounds on iOS browsers though setting config on

[sakabar]

Abstract

No inspection voice sounds on iOS browsers though I set inspection setting.

Reproduction

1. Use iOS13.6, Google Chrome 85
2. Go https://cstimer.net/
3. Set config : timer -> use WCA inspection : Always
4. Set config : timer -> voice alert of WCA inspection : male voice
5. Set config : timer -> Volume voice : 100
6. Turn up the volume of the iPhone
7. Unset silent mode of the iPhone
8. (Optional) Check sound : tools -> metronome -> start. It sounds.
9. Start timer and wait for 8 seconds.
10. "8s!" is shown, but no voice sounds.

Probable cause

The iOS audio restriction. It allows to sound only when a user touched display.

I'm running into a similar issue on macOS (11.0.1) Safari 14, but works fine on Chrome.
