| 术语 | channel voice encoder |
| 释义 | channel voice encoder 信道声(音译)码器 A voice encoding and decoding device that uses speech spectrum compression of up to 90% by separation of the speech frequency band into a number of subband channels by rectifying the signal in each channel. The resulting direct-current (DC) signal represents a timevarying average signal for the subb and. These outputs are multiplexed with a separate channel conveying the fine structure characteristics of the original speech necessary in order to reconstitute the original voice by decoding at the receiver. 利用压缩多达90%的声音频谱压缩技术而设计的一种声音编码和解码装置。它是把声频带分成许多 子带信道,通过调整每个信道的信号来实现的。产生的直流信号代表子带的随时间变化的平均信号。这些输出经多路复合,由一个独立的信道传送 原始语言的精细结构特征,为的是接收器的解码器能够重构原来的语音。 |
