| 1. | Acd absolute cardiac dullness
绝对心浊音 |
| 2. | At the same time , according to the rpt difference between voice and unvoice , speech phonemes are classified
根据清音和浊音在多维相空间中的不同空间分布特性，对语音音素进行了分类。 |
| 3. | Where symbols appear in pairs , the one to the right represents a voiced consonant . shaded areas denote articulations judged impossible
音标成对出现时，左边为清音，右边为浊音。涂色的部分已判定为不可能发音的组合。 |
| 4. | Based on the speech produce model , we find the reason of periodicity disappearance and the extremum number increase by analysing the character of speech signal when the glottal closes
于是从语音产生模型入手，详细的分析了声门闭合时刻语音信号的性质，找到了浊音信号经过小波变换后周期性消失、极值点个数增多的原因。 |
| 5. | 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。 |
| 6. | 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。 |
| 7. | First , after deeply investigating help model , a harmonic related voicing detection algorithm based on mse criterion is developed , with the knowledge that voicing algorithm can be showed by degree of harmonic relation
首先，本文通过对help算法的深入分析，根据语音信号谐波相关程度能反映浊音度强弱的性质，开发了一种基于最小均方误差准则的谐波相关浊音度参数提取方法。 |
| 8. | According to the different characteristics between signal and noise on wavelet transform domain , also considering the voiced and unvoiced speech has different features , a modified method of speech denoising which is using a changing threshold at different scales is proposed
摘要分析了信号和噪声在小波域的不同特征表现，并根据语音中浊音和清音的特点，提出了一种改进的多尺度多阈值的小波域语音去噪方法。 |
| 9. | That is , using a soft thresholding to remove noise components from the wavelet coefficients of the voiced and unvoiced speech in noisy speech respectively in a different way , which is not only removing noise but also is preventing the quality degradation of the unvoiced sounds and enhancing the signal - noise ratio
该方法采用软限幅函数对浊音和清音信号的小波变换系数作不同的阈值处理，既抑制了噪声，又减少了语音段信息的损失，提高了信噪比。 |
| 10. | In studying the different methods of indicating the pronunciation of a chinese character by using two other characters between s . 2055 and other dictionaries of rhyming words , the author found what showed in s . 2055 might be some characteristics in oral language at that time , e . g . the voiced sound and voiceless sound use same initial consonant for the voiced sound had been voiceless ; there was misuse for the initial consonant between the group of zhi and the group of zhao
摘要本文通过研究s . 2055与其他韵书不同反切，认为所反映的可能是当时口语的一些特点：浊音声母与清音有混用，浊音已经清化了；知组声母与照组包括二等与三等有相混的现象；东冬钟归字混乱，三部不分；支脂之三韵也有交涉；微韵“蕲”存在之韵的又音； “解”字有平声一读。 |
