Multiple experiments using artificial intelligence algorithms to improve call quality in Microsoft Teams chats have resulted in significant improvements in audio quality in conversations, Microsoft said Monday. Users may no longer need to use headsets for silent calls and other audio issues.
It is known that the company started development in this area years ago and added the ability to partially filter out background noise from other people’s conversations, barking dogs, etc. Now the Teams development team has announced new improvements.
Users now experience better audio quality when making calls with Teams without the need for special headsets. Often the microphones and speakers on computers are placed side by side, creating a loop effect where the sound from the speakers is picked up by the microphone and retransmitted by the speakers – this is why headsets are so common today. Microsoft said they were able to compensate for this error with an “echo cancellation” system. In addition, the company uses a “de-reverb” system to eliminate echoes from the audio stream in rooms and uses other equally important algorithms to improve two-way communication.
True, Microsoft does not explicitly state that headsets are no longer needed, but the new improvements in the voice communication system allow you to avoid buying additional devices – models of acceptable quality in this area cost at least $ 40 or even $ 100.
Video processing has also been improved. Teams now offers automatic brightness adjustments when the webcam takes a picture, making the user look a little better than usual in chat. In addition, a “soft” focus is applied when the AI system thinks it’s necessary to improve the image of the chatter user contributes. Finally, the Teams service has applied a system to optimize the content shared by the user, both when transferring videos and photos.
Microsoft has already applied functions based on artificial intelligence algorithms in the past. For example, the eye contact function helps to give the impression that the user is looking at the other person (even if that is not entirely true). Initially, the feature was only tested on the Surface Pro X. In April, Microsoft introduced the Voice Clarity feature on Surface Laptop Studio, which automatically optimizes volume when the user turns away from the computer or just walks around the room.
