The first part of the paper is designing the testing project for grounding resistance and insulation resistance in a new way . using 16bits ad converter with programmable control amplifier replaced the way which used changing resistance to change measure range . lt is not only improved testing precision and develop the system expediently , but also reduced the area of the circuit boardwith the new way . in order to make the electric implement safety testing system have upstanding expansibility , the software and hardware of the system adopted the modularization design . adopted mcu atmegal28 as a master mcu which control mmi , realtime clock and communication with slaver mcu . atemga8 as the slaver mcu to realize testing function . so it is easy to add or reduce the testing project . the testing implement system has been developed successfully , and the comments for the system is that it has high precision , high expansibility and easy maintain . but considering the electric implement system should have intelligence and humanity abi lity . so this paper bring forward a scheme of electric equipment safety testing embedded system with speech control . after introduce the basic theory of speech recognition , the paper expatiate the characters of this system . the system is a noise conditon , not special people , small glossary , insulation word system . with these characters design the speech recognition as fellow . utilizing cross zero ratio and short energy to ensure jumping - off point and end point ; adopting mfcc as the character parameters of speech recognition ; the character parameters than be recognized by dtw . in order to ensure the credibility of this project , first realized by matlab in computer 在介绍了语音识别的基本原理后,阐述了本系统的特点:本系统是一个噪声环境下非特定人、小词汇量、孤立词的语音识别系统。根据本系统的这些特点设计了如下语音识别方案:利用过零率和短时能量相结合的方式确定语音端点;采用mel频率倒谱系数( mfcc )作为语音识别的特征参数;得到的特征参数最后通过动态时间规整( dtw )的模式识别方法进行识别。为了确保本系统实现方案的可靠性,首先通过计算机利用matlab软件来仿真,在算法仿真实现后又进一步增加环境的复杂性:加上较大的环境噪声、突发性的噪声等,再通过修改参数、修改参考模板、两级识别等各种提高语音识别精度的方法来提广东工业大学工学硕士学位论文高识别率。
