查询词典 vocoder

As an example, using the standard AMR-NB (Adaptive Multi Rate compression, narrow band) vocoder C reference, the CEVA-X1622 DSP core required just 19 MHz when compiled out-of-the-box (for worst-case frames and streams). In comparison, other licensable solutions require more than 45% higher speed for the same out-of-the-box compiled code.

以使用标准窄带自我调整多速率压缩的C语言语音编码器为例，CEVA-X1622 DSP内核在编译现成可用的代码时，仅需19 MHz速率；而其它可授权解决方案却需要高百分之四十五以上的速度，才能编译同样的现成代码。

A method for protecting channel error code resistance ability of low speed vocoder includes applying improved Chinese plain code and BCH code to separately protect voice parameter in voiceless and voiced sound frames at coding end, using BCH code to recover relevant parameters of voiceless sound frame and using maximum post verification probability rule to recover parameter of voiceless sound accurately for voiced sound frame then using line spectrum to parameter anti-error code algorithm to recover line spectrum to parameter at decoding end.

该方法在编码端改变2.4kb/s SELP编码后清音帧清浊音参数的发送模式；采用BCH码和改进的(7，4)汉明码分别保护清音和浊音帧中的语音参数；在解码端，根据信源信道的联合特性采用分支判决确定清浊音；对于清音帧采用相应BCH码恢复出对应参数，对于浊音帧采用基于长时统计特性的最大后验概率准则恢复清浊音参数，并解码出线谱对参数第一级并对残留误码的线谱对参数采用线谱对参数抗误码算法恢复。
