I was so frustrated the other day, thinking to myself, I can dictate using my phone’s keyboard, why can’t I do this with my Windows 10 computer? Cortana doesn’t do it. Dragon is annoying. But… guess what? It’s built in to Windows 10! Just hit Windows Key-H and the dictation function pops up! Amazing!
