Hangouts Meet live captions is now available on iOS. Support for live captions on Hangouts Meet was announced for the web and Android earlier this year. Google has brought that same captions support to the Meet iOS app.
Please note that when you turn on captions, it will only be visible on that particular device. In order for other participants in the meeting to see captions, they’ll have to turn it on for their devices as well.
Currently, live captions are only available in English. Additionally, captions will not appear in a recording of a meeting.
