Realtime Captioning of PowerPoint Presentations
The realtime captioning feature in PowerPoint has more options than the one in Google Slides. In PowerPoint you can choose where you want the captions to appear when you are presenting in full screen. You can also specify the language that you are speaking in and the language that you want the captions to appear in.
Realtime Captioning and Translation of PowerPoint and Google Slides
If your default presentation creation tool is Google Slides, but you want to use the translation features of PowerPoint, you’re not out of luck. You can create your presentation in Google Slides then download it as a PPTX file. Once you have downloaded it to your desktop, open the file in PowerPoint and you can use the translation features!
