digital speech communication meaning in English
数字式语言通信
数字言语通信
数字语言通信
Examples
- Directly digitizing of speech signals needs too much high bit rate in digital speech communication , thus compression and coding of the speech signals is essential in the process to increase the efficiency of transmission and storage , as well as the channel capacity
数字语音通信中,语音信号直接数字化所需的数码率太高,为了提高传输和存储的效率,充分利用信道容量,必须对数字语音信号进行压缩编码。 - Digital speech technology has been widely used in many fields of communications in recent years , but it is just at beginning to use acoustical wave to implement underwater digital speech communications , which mainly results from the bandwidth - limited underwater acoustic communications channel and its high temporal and spatial variability
目前，数字语音技术已广泛应用于许多通信领域，但是在水下利用声波进行数字语音通信却是刚刚起步的新技术，这主要是由于水声信道有限的通信带宽及其时变、空变等特性所决定的。
