surd meaning in English
adj.

n.
【数学】不尽根，无理数；【语音】无声音，清音〔p，f，s，t,k 等〕。
Examples
- This ab - surd situation occurs because laws are made , en - forced , and reported on by lawyers
这种荒诞的情形是因为法律是律师制定、实行和提出报告的。 - 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
清音和浊音在安排短时预测和长时预测方面的问题；短时预测和长时预测相互包容性问题；提高算法的鲁棒性等方面问题。 - 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
在人类语音的浊音段，声带发生较低频率的振荡，语音信号呈明显的准周期性，而在清音段，语音信号则类似于白噪声。 - 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
本文从声学理论出发，剖析了语音产生的机理，综合考虑声道、激励源和嘴唇辐射三方面的因素，建立了一个完整的、线性的和时变的语音产生的离散系统模型，得出两次声门闭合事件之间的时间间隔就是基音周期的结论。 - 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
本文根据语音信号的混沌本质，利用分形理论研究了汉语连续语音中的音节分割问题，提出了基于方差分形维数的音节分割方法，并详细分析了该方法的性能，它能很好地解决了无声与有声、浊音与清音间的分割问题，但很难解决浊音间的分割问题，当浊音相连且过渡段较短时，该方法无法实现它们之间的分割。
