英汉例句

• based on the model of mbe, the paper researches the arithmetic of pitch period calculation, which includes speech signal preprocessing, initial pitch estimation, pitch refining.

  基于mbe模型，首先研究了语音信号的基音周期估计算法，包括语音信号预处理、基音周期粗搜索与细搜索；

• the algorithm for pitch period search with mbe model is complex in calculation and low flexible.

  mbe模型的基音周期搜索算法存在着运算量大，抗噪性能一般等缺点。

• the snr in public environment of whispered speech is lower than normal speech and the former hasn't pitch period and its formants are not obvious, so whispered speech enhancement is harder.

  相对于正常语音来说，耳语音在公共场合的信噪比较低，而且没有基音周期，共振峰不明显，所以耳语音增强具有一定的难度。

• this improved algorithm can not only omit smoothness of pitch period and simplify the whole algorithm;

  改进算法不但可以省略基音平滑这一过程，简化了整个算法过程；

• finally, individual errors in pitch track are corrected by a smoothing method, in which a searching and tentative method together with a judge mechanism of adding or eliminating pitch period is used.

  最后，采用搜索试探的平滑算法，并加入一个增加或者消除周期的判断机制，对基音轨迹曲线中出现的个别错误进行纠正。

• based on the feature of smoothly varying pitch period and the quasi-periodic structure of voiced speech, an algorithm for pitch prediction is presented.

  根据基音周期平滑变化的特点，基于语音信号的準周期性进行了语音信号的基音提取。

• then the speech signal is pitch adjusted according to this pitch contour, where the original signal with time varying pitch period is converted to a signal of constant pitch period.

  然后根据这一轨迹对语音信号进行「基音调整」，将原始的、具有时变基音周期的信号转化为一个具有恒定基音周期的信号。

• in this paper, we present a new method, which is entitled 「the function of area difference」, to detect the pitch period of speech signal.

  本文提出了一种新的检测基音周期的方法： 「面积差函数法」。
