Live Closed Captioning in Microsoft PowerPoint

The Microsoft Office suite has been around a long time. Since 1988 to be exact—in computer years, that’s almost forever. Yet Microsoft is still able to add new, innovative features to the suite, and one of the latest is live closed captioning in PowerPoint.

Closed captioning has been around since the early 70s, but for years it was a manually intensive and time-consuming task. Recent improvements in speech recognition have made it possible to add live closed captioning. That’s exactly what Microsoft has now done with PowerPoint. (To be clear, today closed captioning in PowerPoint is only in Office Insider releases of the Office suite, and only on Windows 10 or macOS® Mojave. Hopefully, it will become available in Office 365 customer releases in the near future.)

Figure 1 shows what closed captioning looks like in Office for Windows running in Parallels Desktop® 14 for Mac on a MacBook Pro® running macOS Mojave:

As with speech recognition on the Mac, the spoken utterances are sent to a special server in the cloud for conversion to text. The end of the video shows that my speech can be translated into Japanese text—one of about 30 supported languages.
