The audio waveform is divided into several pieces according to the pitch period and then the successive pieces with the same semitone are grouped into one segment .

首先利用基音分析技术将整个音频 波形分割为若干基音周期，然后以半音为 单位将连续的基音周期组织成音频段落，并在各个段落内部按指定比例进行缩放。

The design of electrocardiogram analysis algorithm is to mark for the feature point of waveform and measure ST segment level offset .

设计了心电 波形特征点定位算法，对 波形的特征点进行了标定，并测定ST 段电平偏移，从而实现了ST段的 实时分析。

According to difference of speech waveform between transition segment and non-transition segment dividing between sonant is researched using waveform cross correlation . A method of syllable segmentation is presented based on waveform cross-correlation .

为解决浊音之间的分割问题，本文根据语音中过渡 段与非过渡段语音 波形的差异，利用波形互相关性进行了研究，提出了基于波形互相关性的音节分割方法，并进行了实例分析。
