Optimizing Transcription Precision with Intelligent Speakers

When you have activated Intelligent Speaker for your Microsoft Teams Rooms, the meeting transcript is able to not only distinguish between different speakers in the room, but also identify them and attribute them to the correct person. Intelligent Speaker enables critical use cases for Copilot and intelligent recap.

Speaker recognition is enabled by intelligent speakers certified for Teams. Certified intelligent speakers are designed with multiple microphones to provide high-quality audio, maximize accuracy in recognition and transcription, and boast an industry-leading reduction of what is referred to as 'word error rate'.

That said, we get it – intelligent speaker certified Hardware aren't available yet in every Teams Room. That is why we're extending this feature to existing hardware. While we're delighted to extend the capability of speaker recognition to more rooms, it's important to note the quality may not match that of an intelligent speaker certified device. So, it's essential to evaluate the advantages of incorporating an intelligent speaker, especially in crucial spaces where attaining the highest quality transcription and attribution is vital.

Maintain your identity in meetings optimized for Copilot and meeting recap

The most essential input for Copilot in Teams is the identity of each speaker. Copilot needs a meeting transcript, with attribution for every speaker, to deliver meeting summaries, insights, and action items. In a hybrid meeting, without speaker recognition, the video, and audio feed for people in the room would be attributed to the space (for example, Conference Room 1), not the individuals speaking, making it difficult to query individuals’ contributions, summarize everyone’s perspectives, and tackle those to-do items.

Teams Rooms devices use advanced technology called speaker recognition to analyze the distinct vocal characteristics of each speaker, such as pitch, tone, and speaking style, to create a voiceprint for each participant, akin to a fingerprint for their voice.

With speaker recognition, Teams Rooms can identify speakers during live transcription in shared meeting rooms, ensuring clear and precise voice capture for every participant. This allows you to effortlessly track who said what during the meeting through intelligent meeting recap and Copilot.

To enable speaker recognition for your employees, you can set up a voice profile in minutes using the Teams Desktop app. Each person gets a unique voice signature, stored securely in your organization's tenant in the Microsoft Cloud to assure that every contribution is accurately captured in every meeting, enabling Copilot and intelligent meeting recap – and helping you drive your work forward.

Requirements and recommendations

• Teams Rooms on Windows
• To ensure best precision for the transcript, we suggest limiting the number of in person attendees to a maximum of 10 people.
• People to be identified in the room, need to be enrolled with their voice profile and be invited to the scheduled meeting.
• The current limitation for people invited with voice profile is currently 20.
• To support high-quality audio and video during meetings, we recommend that the meeting room has an upload speed of at least 7 Mbps.

Note

We have extended intelligent Speakers to work with all certified microphones. You can try this out for Teams Rooms with version 5.0.111.0 or later.
