In these portion,the article begins the study of tone sandhi from the point view of two-character phrases and three-character phrases,which is also the focus and difficult point as well.On the basis of substantial materials of Dingzhou dialect,the author elaborates its rules and principles of tone sandhi of the general phrases and those with light tones,and reiterative location.the author puts his views as follows: 1.The rules of tone sandhi of two- character phrase are simple and unitive. 2.The complex of the phrase with light tones lies in the combination of the first tone and light tone.In the case,there are two different pronunciations in Dingzhou dialect.The author guesses it is the coexist of ancient pronunciations and common spoken Chinese. 3.The tone sandhi of general three-character phrases on the basis of the rules of that of two- character phrases,using the grammar structure of the three-character phrases as the restricted conduction,which function jointly. 4.The rules of tone sandhi of three- character phrases with light tones are restricted only by that of the two- character phrases with light tones and thus are foreign to grammar structure. 5.The tone sandhi of the words with reiterative location has their own system.

这两章中，作者采用直接调查法，社会语言学方法分别从一般字组、含轻声字组和叠音词字组三个方面对定州方言连读变调进行详尽地描写，文章中既有对连读变调的共时性描写，也有对连读变调历时性推测，总的来讲笔者认为定州方言变调具有一定的系统性，主要表现在以下几个方面：两字组连读变调规律简单统一，含轻声字两字组内部规律较为复杂，但是具有很强的一致性；定州方言含轻声两字组变调的复杂性主要表现在阴平+轻声的组合中，在这种情况下，定州方言有两种读音方式，推测它是语音存古现象和普通话语音并存的结果；一般三字组连读变调以两字组连读变调规律为基础，以三字组的语法结构为制约条件，二者共同发生作用；轻声三字组变调规律只受轻声两字组变调规律的制约，与语法结构无关；叠音词的变调规律自成系统。

Then, this paper introduces the application of COMS in statistical analysis、voice operation demonstrator and phonetic analysis .

接着，介绍了COMS在统计分析、语音合成和语音分析等方面的应用。

Aiming at this problem, this paper utilizes multi-scale continuous wavelet to pre-filtering the signal of voice.

针对现有语音基音检测算法抗噪能力低的问题，利用多尺度连续小波对语音信号进行预处理。

Then the hardware environment and system flow of coding and decoding algorithm of G.723.1 was mainly described. The scheme of transferring speech signal by EDMA was described to reduce the load on DSP core and can be used for multi-channel speech codec.

接着着重介绍了G.723.1编解码算法在DSK6416上实现的硬件环境，系统工作流程，描述了用EDMA传输语音信号的方案，减轻了DSP的负荷，为多通道语音编码提供了可能。

This paper introduced that how resynthesize the neural firing rate by correlogram inversion,how resume the lost information by half wave rectification inversion.and a solution of speech enhancement based on masking properties of human auditory is proposed and implemented,we can not only analyse and resynthesize speech signal ,but also analyse and resynthesize speech signal in noisy entironment with the system.

又根据听觉生理特点提出了抗噪声方案，使我们的语音分析／重构系统不仅可以对无噪信号进行重构，而且还可以在噪声环境下的语音信号进行重构。
