After an unsuccessful visit to the Apple Store, I returned home and did the following to fix my issue with Mickey or Minnie not talking when tapped:
Ensured my phone was on my wifi.
Unpaired the phone.
Hard reset both devices and swiped all apps on my phone.
Paired the Apple Watch again and used the "Restore from Backup" option. I restored to my first backup (the watch is brand new and only had two backups listed).
Even after the re-pairing, the tap to speak time issue was still not resolved. I went to the watch app on the phone. I selected the Mickey Mouse face. I then went to the "Sounds and Haptic" option in Settings. I set the toggle to"Prominent Haptic" and turned the volume all the way up. I turned the haptic strength slide all the way to the right.
I then went back to my watch and tapped on Mickey and it worked again!!! I then changed my haptic and volume settings back to where I usually have them. I am one happy camper. Got worried there for a minute. I hope this helps you!
