Microsoft announced announcing the availability of new Teams features including echo cancellation, adjusting audio in poor acoustic environments, and allowing users to speak and hear at the same time without interruptions. These build on AI-powered features recently released like expanding background noise suppression.
Echo cancellationDuring calls and meetings, when a participant has their microphone too close to their speaker, it’s common for sound to loop between input and output devices, causing an unwanted echo effect. Now, Microsoft Teams uses AI to recognize the difference between sound from a speaker and the user’s voice, eliminating the echo without suppressing speech or inhibiting the ability of multiple parties to speak at the same time.
“De-reverberation” adjusts for poor room acousticsIn specific environments, room acoustics can cause sound to bounce, or reverberate, causing the user’s voice to sound shallow as if they’re speaking within a cavern. For the first time, Microsoft Teams uses a machine learning model to convert captured audio signal to sound as if users are speaking into a close-range microphone.
