If you’ve ever used PowerPoint to present to a group of people, you’ll be familiar with the Slide Show menu to some degree; unless you’re the annoying would-be presenter merely mirroring your primary screen and flicking through their slides without going into the full-screen slide show mode.
When they do it properly, you’ll often see presenters kick off by fishing about with their mouse to click on the little slide-show icon in the toolbar on the bottom. It’s usually quicker to just hit F5 to start, or Shift+F5 to start from the currently-selected slide.
Unfortunately, it’s still pretty common to then see the speaker be surprised because the config of their displays isn’t what they expect – especially the case if they’re sharing their screen on a online meeting, but their laptop is also connected to more than one monitor.
PowerPoint will typically be set up to use Presenter View by default, and the screen that’s being shared will be showing the speaker notes / next slides etc, while the full-screen content is being displayed on the 2nd monitor that isn’t being shared.
To the right of the Monitor setup for presenter view, you may also see an intriguing option that has been added to PowerPoint – automatic subtitling, and translation too. It’s part of the ongoing Office 365 servicing that brings updates on a regular basis.
Choose the language you’d like to display, the location of the subtitles and when you start presenting, the machine will listen to every word you say and will either display what it thinks you’ve said in your own language, or it can use an online service to translate to subtitles in over 60 languages.
There’s an older add-in which achieves much the same thing, if you’re not using O365 – see here for more info. The Presentation Translator addin also allows the audience to follow along and even interact with the presenter using the Microsoft Translator app on their phone.
Windows has a closed captioning setting page that applies to other apps that support it, too, if you’d like to show subtitles on video that has the content already defined.
Closed Captioning is legislated by several countries, for traditionally-broadcast media as well as online video.
You may also want to add captions to videos that you plan to embed – more, here.
