But it is not the same with surd or the alternation of sonant and surd. on the base of the acoustics, a whole linear time - varying discrete speech produce model is established through anatomising the factors including track, driving source and lip eradiation the mechanism of speech in this paper, and we draw a conclusion that the time between glottal closure is pitch period
本文從聲學理論出發，剖析了語音產生的機理，綜合考慮聲道、激勵源和嘴唇輻射三方面的因素，建立了一個完整的、線性的和時變的語音產生的離散系統模型，得出兩次聲門閉合事件之間的時間間隔就是基音周期的結論。 -
One is the relation between long - term prediction and short - term prediction, another is the difference between the surd and sonant in linear prediction, robust of message source encoding is also researched. 3
清音和濁音在安排短時預測和長時預測方面的問題；短時預測和長時預測相互包容性問題；提高演算法的魯棒性等方面問題。 -
Because the speech signal is periodicity at sonant which vocal cords surge in low frequency and similarity to white noises at surd, the pitch can be detected in traditional way through the correlation operation without the speech produce model
在人類語音的濁音段，聲帶發生較低頻率的振蕩，語音信號呈明顯的準周期性，而在清音段，語音信號則類似於白噪聲。 -
In accordance with chaotic essence of speech signals, syllable segmentation in continuous speech is researched by fractal theory. an approach of syllable segmentation using variance fractal dimension is proposed, its performance is analyzed in detail. the method can discriminate between voiced and unvoiced, between surd and sonant, but it can hardly discriminate between sonant
本文根據語音信號的混沌本質，利用分形理論研究了漢語連續語音中的音節分割問題，提出了基於方差分形維數的音節分割方法，並詳細分析了該方法的性能，它能很好地解決了無聲與有聲、濁音與清音間的分割問題，但很難解決濁音間的分割問題，當濁音相連且過渡段較短時，該方法無法實現它們之間的分割。 -
This ab - surd situation occurs because laws are made, en - forced, and reported on by lawyers
