This looks to be a plugin for PowerPoint that will offer some pretty neat features and is described on the website as:
As you speak, the add-in allows you to display subtitles directly on your PowerPoint presentation in any one of more than 60 supported text languages.
Additionally, up to 100 audience members in the room can follow along the presentation in their own language, and on their own phone, tablet, or computer.
There is some obvious scenarios where this functionality will be awesome when you have a multi-lingual audience you’re presenting to, however I can see a lot of value for this within Education as well. One situation would be for students who prefer to be able to read content to deepen their understanding. Having real time transcription (and translation) will certainly be an amazing demonstration of technology that will add real value to students and teachers alike.
This is not an official release yet but you can sign up for the preview here.
