Coding the two classes signal with different way can decrease the bit - rate further 对这两种信号采用不同的编码方式可以进一步降低语音编码速率。
The testing results show that the vocoder can synthesize high - quality speech when transmission rate is set to be 2 . 4kbps 非正式编解码测试表明,本文的声码器能在2 . 4kbps的编码速率上合成出较好的语音。
At the present time , evrc is the best vocoder in the cdma system when take into account both the voice quality and the encode rate 在目前的cdma系统中,综合语音质量和编码速率, evrc是最佳的语音编码器。
So this codec was optimized to represent speech with a high quality at the above rates using a limited amount of complexity Tetra语音编解码acelp算法以低于4 . 8kbit s的编码速率达到了令人相当满意的语音质量。
The evrc vocoder is varialbe rate , the maximal encode rate is skbps , its voice quality is closed to qcelp - 13k , and has better ability of anti - disturbance Evrc声码器是可变速率的,最大编码速率为8kbps ,在话音质量上接近于qcelp - 13k的语音编码器,且具有更好的抗干扰能力。
