Body (from Message Center)

[Introduction]

We’re expanding the Interpreter agent in Microsoft Teams to include real-time speech-to-speech interpretation for Teams calls. This brings the same functionality previously available in meetings to calls, enabling users to speak and listen in their preferred language.

This message is associated with Microsoft 365 Roadmap ID 526777 and applies to Teams for Windows desktop.

[When this will happen:]

Targeted Release: We will begin rolling out early January 2026 and expect to complete by mid-January 2026.
General Availability (Worldwide): We will begin rolling out late January 2026 and expect to complete by early-February 2026.
Note: Government and Special clouds are not supported at this time, and there is no timeline for availability.

[How this affects your organization:]

Who is affected: Users with a Microsoft 365 Copilot license participating in Teams calls.

What will happen:

Interpreter can now be enabled during Teams calls (previously meetings only).
Users can:
- Choose their listening language.
- Adjust audio balance between original and interpreted speech.
- Select a voice option, including a simulated version of their own voice for interpretation.
No additional setup is required for meetings; this update applies only to Teams calls.
Interpreter works best in structured conversations and may not be ideal for fast-paced exchanges.

[What you can do to prepare:]

If you want to enable Interpreter for calls, configure policies using:

Enable users to use interpreter in calls: Set-CsTeamsCallingPolicy (MicrosoftTeams) | -AIInterpreter | Microsoft Learn
Enable users to user to use the voice simulation feature while being AI interpreted in calls: Set-CsTeamsCallingPolicy (MicrosoftTeams) | -VoiceSimulationInInterpreter | Microsoft Learn

Communicate to users that Interpreter works best in structured conversations and may not be ideal for fast-paced exchanges.
Update internal documentation and helpdesk guidance.

[Compliance considerations:]

Consideration	Explanation
Does the change introduce or significantly modify AI/ML or agent capabilities that interact with or provide access to customer data?	Interpreter agent uses AI-driven speech-to-speech interpretation and voice simulation, which processes real-time audio streams from Teams calls and meetings. The feature does not provide direct access to raw customer data for users or admins; it processes audio for interpretation purposes only. Data handling follows Microsoft’s compliance and privacy standards.
Does the change provide end users any new way of interacting with generative AI?	It extends Copilot’s AI capabilities into live audio experiences
