双语例句

• In the standard MELP algorithm the value of the relevant is small for the irregular cycles of the speech signal and we mistakenly believe that it is unvoiced. So it will introduce noise.
  在标准MELP的算法中，对于那些包含有不规则周期的语音信号段，计算得到的互相关值较小，把它误认为是清音，因此会引入噪音。
• There are different characteristics in the relationship of wavelet transform coefficient and scale when the speech signal and the random noise are transformed on the different scale, and noisy sounds and unvoiced sounds are also characterized with different features.
  语音信号与随机噪声在不同尺度上进行小波变换时，其小波变换系数和尺度大小的特性关系存在着不同的特征表现，而且，浊音和清音也各有其特性。
• A Simple Method of Unvoiced/ Voiced Classification of Speech Signal
  一种组合参数的语音信号清/浊音判决方法
• Because of complex and non-stational of speech, especially unvoiced speech has no clear time and frequency character, which is very similar to white noise, classic noise reduction method is unsatisfactory.
  由于语音信号的复杂性和非平稳性，特别是清音没有明显的时域和频域特征，非常类似于白噪声，传统的降噪方法不尽人意，尤其是对宽带噪声的抑制效果不是十分明显。

• To prevent the quality degradation of the unvoiced sounds during the denoising process, we first separate unvoiced regions from noisy speech and then apply the thresholding method to them in a different way from other regions.
  同时，为了防止在抑制噪声的过程中对语音的清音段信息造成损失，首先对语音信号进行了清浊音判别，然后针对不同的判别结果对清音段语音和浊音段语音采用不同的阈值处理方法。
