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，提出了基于方差分形維數的音節分割方法，并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。
In this thesis , the research focuses on pitch detection techniques of the low - rate wi speech coding . aimed at the problems of voiced - unvoiced error , pitch doubling and halving , accuracy of pitch detection and pitch quantization , a series of pitch detection techniques including pre - processing , pitch detection and pitch quantization were proposed 本文就低速率wi語音編碼中的基音檢測技術進行了深入研究,針對基音檢測中的清濁誤判、基音加倍減半、基音檢測精度及基音量化問題,提出了包括基音檢測前端處理、基音檢測算法及基音量化的一整套基音檢測技術。
Experimental results in different noises and snr indicated that this vad algorithm can divide speech segments from non - speech segments accurately and reduce voiced - unvoiced error obviously . ( 2 ) an improved dct - hn speech decomposition algorithm based on the harmonic - noise model is presented 不同噪聲、信噪比下的實驗結果表明,該算法可以準確區分語音段與非語音段,明顯降低了基音檢測中清濁誤判現象的發生; ( 2 )基于“諧波-噪聲”模型提出了一種改進的dct - hn語音分解算法。
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 該方法采用軟限幅函數對濁音和清音信號的小波變換系數作不同的閾值處理，既抑制了噪聲，又減少了語音段信息的損失，提高了信噪比。
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 摘要分析了信號和噪聲在小波域的不同特征表現，并根據語音中濁音和清音的特點，提出了一種改進的多尺度多閾值的小波域語音去噪方法。
And a new pitch extraction algorithm , an active / inactive frame decision algorithm and a voiced / unvoiced frame decision algorithm are developed with the aims to improve the quality of the vocoder and reduce its overall computation load 本文引入了一種新的基音周期計算方法，靜音幀判決算法，清音幀判決算法，清濁音信息接收端重建等新算法，提高了合成語音的質量，降低了算法的總計算量。
What else i can do to avoid dealing with unvoiced frustration and uncomfortable feelings 我還能做些什么來躲避那些說不出的失意和令人不快的感情呢。
The two parties made an unvoiced pact not to reveal the case to the press 雙方已達成默契，不將此案披露給媒體。
