I am not an Apple Watch person, but several people in my family have them. The other day my daughter received a phone call on her iPhone, but she took the call on her Apple Watch 4. I noticed she raised the Watch to speak. Then, I came across this article which explains how to activate the “Raise To Speak” feature on the Apple Watch 4. I thought this was pretty handy. If you have an Apple Watch (has to be version 4), you may wish to read the article on how to activate this feature.
