Manage voice recognition technology controls for an Intelligent Speaker

An Intelligent Speaker uses voice profile information to recognize who said what in live transcription. When a Microsoft Teams Rooms for Windows meeting room is equipped with an Intelligent Speaker, live transcription can be used during the meeting. This article explains how you, a tenant admin, control the voice profiling that's used for voice recognition to generate live transcription. You can control to what degree the organization is using voice recognition and the following features:

  • Edit the speaker's name in transcripts.
  • Change the speaker of a single utterance in the transcript or change the speaker in all the utterances in the transcript (but not on future transcripts).
  • Change the speaker identification for the people who are listed in the meeting.
  • Remove the identification of one or more utterances identified as that speaker, on every transcript.

Review Intelligent Speaker requirements

An Intelligent Speaker includes a special seven-microphone array. The system uses voice profile information to identify voices of up to 10 people in meeting rooms.

The following items are Intelligent Speaker requirements:

  • The customer tenant must be located in the U.S. (North America).1
  • The meeting room should have a maximum of 10 people present in person.
  • The meeting room has an upload link of minimum 7 Mbps.

1 An Intelligent Speaker and associated voice profile and usage will only be available in EN-US language and for US (NA-US region) tenants. Both conditions must be true for a tenant user to enroll and use an Intelligent Speaker for attributed transcription.

Set up an Intelligent Speaker

An Intelligent Speaker connects directly using USB to the Teams Rooms console. For best results, a Yealink brand Intelligent Speaker should be used with a Yealink brand console.


A Yealink Intelligent Speaker must be used with a Yealink console.


We don't support an Intelligent Speaker connected to Logitech Surface Pro Microsoft Teams Rooms. There is a known issue that Teams Rooms can't recognize the Intelligent Speaker through the dock.

An Intelligent Speaker should be placed at least 8 inches (20 cm) away from walls and large objects, such as laptops. If the Intelligent Speaker USB cable isn't long enough for your setup, use cable extenders.

  1. Sign in to the console as administrator.

  2. Set the Teams device settings to match the Intelligent Speaker microphone and speaker. You can also do this through the TAC portal instead of at the room console.

EPOS and Yealink devices should have "EPOS" or "Yealink" prefix and contain "UAC2_RENDER" in the speaker name and "UAC2_TEAMS" in the microphone name. If you don't find these microphone and speaker names in the dropdown menu, restart the Intelligent Speaker device.

Enable an Intelligent Speaker user recognition

Voice profile data can be used in any meeting with an Intelligent Speaker. See Teams meetings policies and the PowerShell meeting cmdlets for information on the meeting settings.

The voice profile data of the user is created when the policy is set to distinguish or a non-meeting invitee walks in during the meeting. The voice profile data is dismissed at the end of the meeting.
