Each users' image and voice can be reached at others' terminals. As to the signs of image, many windows can be opened on a termined and the participarts' images can be on the screen as well. However, as to voice, no matter how fast the speed of transmission is, it is common for listerners to find the great distinctions, between the voice of communicanons and that of face-to-face communications, which debases the quality of multipoint communications. Therefor, it is vital important to take measures to solve the mixed voices of multipoint communications during a high quality system of multipoint communications. In this article, we try to solve the trouble of voice in speech mixing. The theory of queue is applied in the analysis of voice data of multipoint communications, which forms the mathematic model. From the model, the equations of estate transfer will be obtained. And then through computer simulation, we get the results of equation and data we wanted are presented as well. With the model of queue, massive experiments and curvilinear regression, the relation among the scale of communication, the threshold of working, and the queue buffer is found. Therefore the expansibility problem of voice data of multipoint communications with real-time speech mixing is solved in the last part of this paper.展开更多
