Systems and methods for processing meeting information obtained from multiple sources

A method for processing audio information, comprising:

• receiving, by a communication interface, a plurality of audio streams obtained by multiple terminal devices, wherein each of the multiple terminal devices obtains one or more of the plurality of audio streams;
• beamforming the plurality of audio streams based on a spectral mask indicating signal and noise presence probabilities;
• synchronizing the beamformed audio streams;
• determining signal-to-noise-ratio (SNR) indicators associated with the synchronized audio streams;
• selecting, from the synchronized audio streams, a candidate audio stream based on the SNR indicators, wherein the SNR indicator associated with the candidate audio stream indicates that the candidate audio stream has a higher average SNR than that of a predetermined number of other audio streams;
• and
• generating a synthesis audio stream including at least a portion of the candidate audio stream.

A non-transitory computer-readable medium storing instructions that are executable by at least one processor to cause performance of a method for processing audio information, the method comprising:

• receiving, by a communication interface, a plurality of audio streams obtained by multiple terminal devices, wherein each of the multiple terminal devices obtains one or more of the plurality of audio streams;
• beamforming the plurality of audio streams based on a spectral mask indicating signal and noise presence probabilities;
• synchronizing the beamformed audio streams;
• determining signal-to-noise-ratio (SNR) indicators associated with the synchronized audio streams;
• selecting, from the synchronized audio streams, a candidate audio stream based on the SNR indicators, wherein the SNR indicator associated with the candidate audio stream indicates that the candidate audio stream has a higher average SNR than that of a predetermined number of other audio streams;
• and
• generating a synthesis audio stream including at least a portion of the candidate audio stream.
