If you want to caption a presentation for people who are deaf or hard of hearing, you typically have to do it yourself. Google might just save you that trouble — it’s launching an automatic closed captioning feature for Slides. Plug a microphone into your computer, hit a “CC” button and Slides will automatically caption your speech as you walk through the presentation. As the captions arrive in real-time, you don’t have to worry about stopping on each slide to give your audience a chance to read.
