Call audio mixing processing method for voice activity analysis
A recently granted patent (Publication Number: US11887618B2) discloses a call audio mixing processing method that involves obtaining call audio streams from terminals of call members participating in a call. The method includes performing voice analysis on the call audio streams to determine voice activity corresponding to each terminal, adjusting the call audio streams based on voice adjustment parameters, and performing mixing processing to obtain a mixed audio stream. The voice analysis is based on subband power spectra and voice presence probability in audio frames, allowing for precise adjustment of the call audio streams.
Furthermore, the method involves encoding and decoding the call audio streams, as well as adjusting the mixed audio stream based on terminal performance. The voice analysis process includes voice detection, determining voice frames and energy values, and calculating signal-to-noise ratios. The method also includes determining voice adjustment parameters based on single-frame signal-to-noise ratios and historical data. The processing circuitry is configured to perform these operations, ensuring efficient and accurate mixing of call audio streams. Overall, the patent presents a comprehensive approach to call audio mixing processing, enhancing the quality and clarity of audio streams during calls.
