I've had this happen three times where my Apple Watch will not speak, at all. I've turned VoiceOver off and on. I've used the three-finger double-tap to turn speech off and on, and still nothing. Haptics are working, but absolutely no voice. I have the Apple Watch 8 and I think it's WatchOS9.2. I've had to unpair and pair it again all three times. VoiceOver volume says 100 percent and haptic volume is 100 percent.
Any suggestions are welcome. Thank you so much.
