| 中文摘要: |
| 本文应用Short改进了的短时非线性预测方法对正常语速的汉语音节和短语进行了分析研究,揭示了汉语语音中浊音和清音的短时非线性预测能力的差异,并且发现这种差异即使在强背景噪声下仍能用短时非线性预测方法加以辨别。这些为浊音和清音的切分提供了一种可能性手段。 |
| 英文摘要: |
| This paper studies the characteristics of Chinese speech using the short-term nonlinear prediction method improved by Short. It is found that the accuracy of the short-term predictions of voiced speech signal and unvoiced speech signal is distinctly different, even in a strong noise background. So the method offers a potential method to divide the voiced speech from the unvoiced. |
