    • In a speech packet switching system, an input speech signal to a speech packet transmitting station is converted to a digital signal to form speech data blocks, which are discriminated to talkspurt blocks and silence blocks, and only the talkspurt speech blocks are packetized and transmitted through a speech packet switching network. In a receiving station, a series of speech packets received in one talkspurt period are temporarily stored in a variance absorbing buffer to compensate for a variance of transmission delay times resulting from the transmission through said speech packet switching network to add variance absorbing times to the speech packets depending on the transmission delay times of the respective speech packets. Then the speech packets are sequentially reproduced. A size of the variance absorbing buffer is determined by a variance of the transmission delay times of the speech packets received in one talkspurt period and the size of the variance absorbing buffer for the next talkspurt period is dynamically changed based on the determined size. A constant speech quality is assured to a change of the variance of the transmission delay times of the speech packets due to a change of traffic in the speech packet switching network.
    • 在语音分组交换系统中,向语音分组发送站的输入语音信号被转换为数字信号,以形成语音数据块,这被识别为话音突发块和静音块,只有话音突发语音块被打包并通过 语音分组交换网络。 在接收站中,在一个话音突发时段中接收的一系列语音分组临时存储在方差吸收缓冲器中,以补偿由通过所述语音分组交换网络的传输导致的传输延迟时间的差异,以向语音添加方差吸收时间 分组取决于各个语音分组的传输延迟时间。 然后语音分组被顺序再现。 方差吸收缓冲器的大小由在一个通话突发时段中接收的语音分组的传输延迟时间的方差确定,并且基于所确定的大小,下一个话音突发周期的方差吸收缓冲器的大小被动态地改变。 由于语音分组交换网络中的业务量的变化,确保语音分组的传输延迟时间的方差的变化。
