As an experiment, I said aloud the words “comma” and “period.”
Here is the unedited dictated first thing I said: “I am dictating on my phone. Lets see if it recognizes what I say. I am trying to make a sentence, and will see if it understands it.”
Wow! I’m not sure how I’ll use this, but it’s certainly a lot faster than typing on the tiny keyboard. (With my thumbs, so I don’t look old.)
