Speaking clock with robotic voice

Hello shteryan,

Thank you for reaching out to Apple Support Communities.

We were able to find this:

"Tell time on Apple Watch

There are several ways to tell time with your Apple Watch.

• Raise your wrist: The time appears on the watch face, in the clock in grid view, and in the top-right corner of most apps.
• Hear the time: Open the Settings app  on your Apple Watch, tap Clock, then turn on Speak Time. Hold two fingers on the watch face to hear the time.
• Apple Watch can also play chimes on the hour. In the Settings app  on Apple Watch, tap Clock, then turn on Chimes. Tap Sounds to choose Bells or Birds.
• Feel the time: To feel the time tapped out on your wrist when Apple Watch is in silent mode, open the Settings app  on your Apple Watch, tap Clock, tap Taptic Time, turn on Taptic Time, then choose an option. See Use Taptic Time.
• Note: If Taptic Time is disabled, Apple Watch might be set to always speak the time. To be able to use Taptic Time, first go to Settings  > Clock, then turn on Control With Silent Mode under Speak Time.
• Use Siri: Raise your wrist and say “What time is it?”"

More details can be found here: Tell time on Apple Watch

While we didn't see an option to change the voice, we would recommend leaving feedback for Apple directly.

You can do so by going to Watch

Cheers!

Hey there shteryan,

Thank you for those additional details. If you haven't already, you can see if restarting your Apple Watch may help. Restarting can refresh the watchOS and possibly help resolve unexpected issues. If needed, below shows how:

"How to restart your Apple Watch if you have watchOS 9

1. If your Apple Watch is charging, take it off the charger.
2. Press and hold the side button until you see the power button  in the upper-right corner of the display.
3. Tap the power button.
4. Drag the Power Off slider.
5. After your watch turns off, press and hold the side button again until you see the Apple logo."

Those steps are from this article: Restart your Apple Watch - Apple Support Please let us know if that helps or if you've already tried that.

Take care!
