I just discovered voice to text on the new phone

I bought a new cell phone the other day and have been getting used to the virtual keyboard by entering my 255 contacts in by hand.   48 hours later, I feel comfortable with the keyboard, although it’s neither quick nor easy yet.  I’m reading the manual over a couple of times and just discovered the “voice to text” feature.   I just tap on the little microphone image, then  speak the words and it types them.   Who knew??!!  Yay for modern technology!
