(Updated) Microsoft Teams: Enhancements to Interpreter and multilingual meeting experience

Microsoft Teams enhanced its multilingual meeting experience by adding automatic spoken language detection, a “Preparing” status indicator for the Interpreter, and clearer settings explanations. These updates, available to Microsoft 365 Copilot users, roll out December 2025 across multiple platforms with no admin action required.

Updated December 16, 2025: We have updated the content for clarity. Thank you for your patience. 

[Introduction:]

We’ve improved the multilingual meeting experience in Microsoft Teams, focusing on the Interpreter agent to make it more seamless and intuitive. These updates help participants communicate more effectively in multilingual meetings.

• Automatic spoken language detection when Interpreter agent is enabled - Teams now automatically detects and updates the spoken language across Interpreter, live captions, and transcription—no manual setup required:

 

• “Preparing” status indicator - A new visual cue shows when the Interpreter is initializing, helping users know when it’s ready:

 

• Simplified settings - Interpreter settings now include clear explanations for each option, making setup easier and reducing confusion:

 

Note: When Interpreter is turned off, live captions and transcription still work, but automatic language updates won’t apply—so captions may become inaccurate if participants switch languages mid-meeting.

Important: Interpreter is only available for Microsoft 365 Copilot licensed users.
