双语例句

• The surface electromyogram ( SEMG) signal of six unvoiced Chinese vowels are detected from the skin surface of zygomaticus major and anterior belly of the digastric, with AR model coefficients, cepstral coefficients and MFCC coefficients of SEMG signal taken as the original eigenvector.
  从颧肌和二腹肌前腹的皮肤表面检测无声发出6个汉语元音的表面肌电信号（SEMG），以该肌电信号的AR模型系数、倒谱系数和美尔倒谱系数作为原始特征向量。
• 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。

  提出了基于肌电信号（EMG）的无声语音识别系统。
• In this paper two relatively optimum features that can be used in isolating syllables in continuous Chinese speech have been generalized, through characteristics analysis of Chinese speech and the DFT spectral characteristics of various phonemes, especially the DFT distinction of voiced/ unvoiced sounds.
  本文通过对汉语语音的特性分析，及各类音素的DFT谱特性，特别是清/浊音的DFT谱差异的研究，概括出了可用于连续语音音节分割的两个相对最佳的动态特征；
• 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.

• But the unvoiced sound is more like a white noise signal, the voiced sound reflects the movement of the vocal tract and is a periodic signal, so more speaker information is contained in the voiced sound.
  由于清音是一种类白噪声的信号，而浊音是一种准周期的信号，反应的是说话人声道变化的情况，浊音包含有更多的说话人信息。
• 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。
