Google Slides can show real-time caption from the speaker’s voice.
It’s good news that Google Slides has a new feature to help your presentation is more convenient for speakers and audiences. With this new feature will automatically create captions while speakers are speaking and show them below the slides.
The feature will use the microphone from the computer that is presenting Google Slides and will catch only voice from the speaker then automatically create and show descriptions below the slides. Which this feature will help your audiences catching contents better than ever. And this feature is now available on every plan of G Suite for end users.
You can check the benefits of this feature from here.

⇢ Help people who are non-native, speakers and audiences
⇢ Audiences still can catch the content in case the audio is not good quality
