摘　　要：将虚拟声技术运用于网络语音会议系统中,利用头相关传递函数对单音频信号进行处理,使之扩展为两路立体声信号,从而对不同的参会者虚拟出带有不同方位感的虚拟声像,模拟出圆桌会议的声像效果,并设计实现了一个简单的基于Windows平台的网络虚拟会议系统。主观测听结果显示,所有测听者均认为添加虚拟声功能后用户体验更好,大部分测听者认为该功能将混乱情况下的语音进行了方位感的梳理,增强了鸡尾酒会效应,使测听人更加容易辨别说话人,也更容易辨识说话人所讲内容。In this paper, the virtual sound technology applied to the network voice conferencing system, the use of head-related transfer function of single-audio signal processing, so that it is extended to two stereo signals, so that different participants virtual out with a different sense of virtual Audio and video, simulation of the round table audio and video effects, and designed to achieve a simple Windows platform based on the virtual network virtual conference system. Subject audiometry results show that all the participants are considered to add virtual sound function after the user experience better, most of the listener that this feature will be chaotic voice of the location of the carding, and enhance the cocktail effect, so that listeners are more likely to identify the speaker, but also easier to identify the speaker＇s content.
