Microsoft added custom backgrounds to the Teams desktop app for Mac and Windows in June 2020: prior to that Teams had only blurred backgrounds to give users a bit more privacy while conducting online meetings from the home.
As Microsoft highlights, "blurring or replacing a background may not prevent sensitive information being visible to other people in the meeting."
Microsoft says these changes to Teams on the web are aimed at small businesses facing "challenges they've never experienced before".
CART captioning on the Teams for the web could be handy for businesses that want to use Teams in the browser. This avoids the need to see captions from a secondary window.
"You can now view captions coming from a CART provider (real-time captioning) within the Microsoft Teams meeting window instead of a secondary window. Follow along with what is being said without having to choose between the captions and the presentation," Microsoft says.
Microsoft enabled live transcription and captioning in Teams for the desktop for 27 languages in September 2021, so now this same breadth in language support for the two services is available for the Teams on the web.
