Have you tried voice typing in Google Docs?

We always recommend that you give it a go before supporting students with the tool.

Voice typing is available in Google Docs under the 'Tools' menu. This accessibility option supports students with typing their work, allowing them to use their voice instead of the keyboard. Not only will voice typing pick up their words, but it will also allow you to format and edit the document too.

Voice typing also allows you to voice type in different languages. When you launch the voice typing option, you are able to select a language from a menu before starting to type.
