Are you getting frustrated by the lack of audio feedback from your Apple Watch when you leave your iPhone at home when running? Fear not, it’s quite a simple fix to get your announcements back.
Using your iPhone, navigate to the Watch application and go to:
General, Language & Region
If the current setting is English (U.K) then this is why you are not receiving voice feedback from your watch. I assume this is something to do with the language pack.
Change the Watch Language to English.
This will then resolve the problem with missing audio cues on your Apple Watch.
