基音

Wavelets transform is used to detect the pitch period of speech signal, and attain a good result.

This method sums a group of sinusoids to synthesize the speech signal, and the frequencies of these sinusoids are multiples of the fundamental frequency.

本算法采用叠加一组正弦波的方法来合成语音，这些正弦波的频率是基音频率的整数倍。

When the detected partials match more that one set of predicted/modeled harmonic relationships, algorithms of the first method are used to select the deduced fundamental.

当检测分音还匹配一个预计的/模型化泛音关系的集时，第一种方法的对数被用来选择推断的基音。

The arithmetic searches for the least central offset through partition speech sub-band and confirms pitch period of the transition sound.

该算法主要通过划分语音子带来搜索最小中心偏移量，较准确地确定过渡音的基音周期。

The following three disadvantages of power spectrum reprocessing method for pitch detection are found: half pitch error and double pitch error with transition sound; easy distortion in noise speech; the complex method of judging voiceless and voiced speech.

本文分析了功率谱二次处理基音检测方法的不足：对于过渡语音，易产生半频或倍频误判；噪声干扰下，检测结果易失真；清、浊音的判断方法复杂。

The thesis first briefly reviews the history of speaker recognition_and then discusses the main theory of it. Feature extraction model, pattern matching model and decision model as the key factors of speaker recognition, several models and algorithm for each part are discussed in detail.

详细地讨论了基音频率、线性预测系数及美尔倒谱系数等特征提取方法，以及动态时间规整、矢量量化、隐马尔可夫模型等模式匹配算法的原理及实现流程。

Normal speech, speech with pitch dithering and speech background noise have been used to test the performance of the optimized algorithm, Speech signal after processed by both proposed algorithms presented obvious periodicity in time domain.

我们设计了普通语音、基音有抖动的语音和带有噪声干扰的语音来检验优化算法的性能。

The philosophical significance attached to the tones in Chinese music led to the belief that the determination of a fundamental absolute pitch and the generation of the other pitches from this fundamental one was a matter of first importance to each dynasty.

中国人给中国音乐里的音赋予了哲学意义，因此认为每朝每代最大的大事是确定基本的绝对的音高，并由此基音推出其他音的音高。

Japanese violinist Akiko Suwanai was the youngest ever winner of the Tchaikovsky Competition in Moscow, and has quickly established herself as a major force among solo violinists with an exquisite tone quality, enhanced by the 1714 Stradivarius violin she plays which used to belong to the legendary Jascha Heifetz

日本小提琴家诹访内晶子是莫斯科国际柴可夫斯基音乐大赛最年轻的冠军得主，之后，她迅速冒起成为炙手可热的独奏家，她的音色敏锐细腻，使用的是曾属传奇小提琴家海菲兹所拥用的1714史特拉瓦里小提琴。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
