Live presentations can be thought-provoking, inspirational, and powerful. This innovative new feature provides captions and subtitles for presentations in real-time. Live captions & subtitles in PowerPoint supports the deaf and hard of hearing community by giving them the ability to read exactly what is being spoken in real-time. In addition, captions and subtitles can be displayed in the same language or in a different one, allowing non-native speakers to get a translation of a presentation.
