Microsoft Teams upgrading the conferencing experience with ML and AI: Know how

Microsoft has been using the machine learning (ML) models for improving the room acoustics so that the users will no longer sound like they are hiding in a cave, will improve the calls from echo, interruptions, and acoustics on the Teams platform

Microsoft Teams upgrading the conferencing experience with ML and AI: Know how

Microsoft has reported that the platform is now using new artificial intelligence (AI)-powered voice quality for adding the improvements in the platform. The artificial intelligence will help in improving the echo, interruptions, and acoustics on the Teams platform.

As per The Verge, Microsoft has been using machine learning (ML) models to improve room acoustics so users will no longer sound like they are hiding in a cave.

Robert Aichner, Principal Programme Manager for intelligent conversation and communications cloud at Microsoft stated in an interview: "While we have been trying our best with digital signal processing to do a really good job in Teams, we have now started using machine learning for the first time to build echo cancellation where you can truly reduce echo from all the different devices." 

Microsoft has been testing this for months and has been measuring its models in the real world to ensure Teams users are noticing the echo reduction and improvements in call quality.

The software maker used 30,000 hours of speech to help train its models and captured thousands of devices through crowdsourcing where Teams users are paid to record their voice and playback audio from their device.

"We also simulate about 100,000 different rooms... the room acoustics play a big role in echo cancellation," said Aichner.

The result is big improvements in-call audio quality, and the elimination of echo that also allows multiple people to speak at the same time, the report said.
