Microsoft Teams has added live transcription, along with speaker attribution, as the battle over corporate communication heats up.

Microsoft Teams has quickly emerged as one of leading corporate messaging platforms, and a part of Microsoft’s business that could one day rival and surpass the web browser in importance.

An important new feature is live transcription in Teams meetings. The feature uses artificial intelligence to analyze the participants and meeting details to accurately transcribe the contents.

Live transcription in Teams uses a meeting’s invitation, participant names, attachments, etc. to improve the accuracy and recognize meeting-specific jargon for each transcript automatically, without any human involvement. This means no one at Microsoft ever sees the meeting’s content, and the models are automatically deleted immediately after each meeting. In addition, Microsoft doesn’t use or store this data for improving its own AI.

Webex, Google Chrome and Zoom all have closed captioning or transcription. Microsoft including the feature in Teams is an important step in maintaining its position in the market.
