Diana Benner at TCEA is celebrating a new feature of Slides by Google - automated Closed Captioning! Just hook a microphone up to your computer and start talking while you are composing Slides, and your speech will be automatically included in your current Slide, using Machine Learning. It is said to be very accurate. Try it yourself. Google Slides Closed Captioning supports only nglish at this time, but Google promises to include more languages soon.
