Abstract: Voice communication method and apparatus and method and apparatus for operating jitter buffer are described. Audio blocks are acquired in sequence. Each of the audio blocks includes one or more audio frames. Voice activity detection is performed on the audio blocks. In response to deciding voice onset for a present one of the audio blocks, a subsequence of the sequence of the acquired audio blocks is retrieved. The subsequence precedes the present audio block immediately. The subsequence has a predetermined length and non-voice is decided for each audio block in the subsequence. The present audio block and the audio blocks in the subsequence are transmitted to a receiving party. The audio blocks in the subsequence are identified as reprocessed audio blocks. In response to deciding non-voice for the present audio block, the present audio block is cached.

Abstract: In an conferencing system in which a plurality of communication devices electronically connect respective participants to one another, a method for mitigating the effects of substantially concurrent audio bursts from two or more of the participants includes identifying a priority attribute associated with each of multiple substantially concurrent audio bursts, comparing the identified priority attributes, and electronically suppressing at least one audio burst as a function of the comparison.
