Google Docs has offered voice typing on the web since 2015 and the input method is now set to get "enhancements"

that will also improve automatic captioning in Google Slides

When viewing a Google document, Tools > Voice Typing opens a floating microphone that accepts input until you click it again.

You can also edit and format with your own voice. The upcoming update will "reduce transcription errors and reduce audio loss," but Google doesn't provide any specific examples.

Google Docs voice typing will also get "expanded availability for most major browsers".

At the moment, the feature is "only available in the Chrome browser" and doesn't work in Safari.

These transcription quality updates will also apply to automated captions in Google Slides that help audience members read/caption your presentation.

We expect this release to lead to more inclusive and accessible user interactions in Docs and Slides.

These features are rolling out now and will be available in full over the next month for free and paid workspace levels.
