Microsoft He has spent the last two years adding new exciting productivity features Teams, And now the company is considering how the basics work thanks to that artificial intellect.

All the readers were at some point on the call where someone has bad acoustics, making it difficult to hear them, or watching two people simultaneously trying to converse, the awkward moment of “No, you go, please.”

Well, given these situations, Microsoft Introduces New Improvements in Sound Quality Using Artificial Intelligence In which the above contexts should improve or even eliminate this daily irritation.

Add sound quality improvements to calls

Microsoft is now using the models Mechanical engineering To improve the acoustics of the room in which the person is, it no longer sounds as if he is hiding in a cave.

“While we did our best to do digital signal processing to do a really good job at Teams, we are now starting to use machine learning to create echo cancellation for the first time where you can really reduce everyone’s echo. Various devices. He explains. Robert Eichner, In an interview with The Verge, Senior Program Manager for Microsoft Smart Talk Cloud and Communications.

Microsoft has been testing this for months and evaluating its models in the real world to ensure this Team users notice reduced echo and call quality improvements.

Manufacturer Software He used 30,000 hours of speech to help prepare his models and arrested thousands of people Devices In collective cooperation, Where team users are paid to record voice and play audio from their device.

“We also simulated about 100,000 different rooms. “Room acoustics play an important role in canceling the echo,” Eichner told the media. The result is a great improvement in the audio quality of the calls and the elimination of echo. Which also allows several people to speak at the same time. All the improvements can be seen in the following video:

How the new AI works in Microsoft Teams

If Teams finds that sound is rotating or ringing in the room, causing superficial audio, the model also converts the recorded audio, and Display it the way team members speak into a short-range microphone.

Is the most impressive part The ability of people to stop each other on calls Microsoft Teams, without the awkward overlay where it is impossible to hear another person due to the echo.

Microsoft is releasing all of these new features in Teams, along with improvements it previously made to AI-based noise suppression. All processing is done locally on the client’s devices, Instead of Cloud.

“We said we want to do this for the client because the cloud is still expensive if we want to make all the calls processed in the cloud, and obviously we have to pass that value on to the client. Explains Eichner To TheVerge.

This means Potentially limiting these significant team improvements to paying clients; And the way things are done on the device means that features like noise suppression are available on 90% of the devices that use Teams.

All of these new Microsoft Teams improvements Already available with Optimize real-time display of text in videos And AI-based enhancements for bandwidth limiting screen sharing or video calling.
