Human brain function similar to the central processing unit installed on the motherboard on the above, it has a superhuman memory and rapid calculation function of precision, it can be scheduled in accordance with the procedures for people to not hesitate to complete the instruction, as well as network traffic as the memory, it can provide more paths and channels to the computer, the faster the computer more efficient, to let the computer voice would also like to assemble a deal with the sound card sound files, as the screen reader software At the same time, prompted the need for sound playback, sound card, therefore the request is relatively high, the best selection of full-featured dual-channel sound card.

类似人脑功能的中央处理器就安装在主板上面，它具有超人的记忆能力和精确快速的运算功能，它能够按照人们预定的程序毫不犹豫地去完成各项指令，还有就象交通路网的内存，它能够提供更多的路径和通道给计算机，使得计算机的运算速度更加快捷，要让计算机能够发出声音还要装配一个处理声音文件的声卡，由于读屏软件所需要同时播放提示声音，因此声卡的要求比较高，最好选用功能齐全的双声道声卡。

For example, an inexpensive 2-channel sound card may be good enough for someone initially, but down the road they may decide that something like the 7.1 channel Sound Blaster Audigy 2 offers the sound quality they really want.

举例来说，一个便宜的双声道的声卡对于初用者来说就足够好了，但是接下来他们可能决定他们所需要的是能给他们提供真正想要的声音品质的7.1声道声霸卡2。

The results are very useful in analyzing the sound field distribution of combination source in the underwater sound channel.

该成果对于分析水声信道中组合声源的声场分布具有一定的参考价值和指导意义。

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。
