| 摘 要： | 送气辅音与非送气辅音是普通话辅音中的一对区别特征,在实际应用中需要寻找与之对应的特征参数。传统的M EL能量参数无法对这对特征进行有效的区别,该文在时频域使用W igner分布,提取基于W igner分布的特征参数作为送气辅音和非送气辅音的区别特征参数。经过一个较大语料库的测试,结果显示新的参数能够有效区别这2类不同的辅音,并且有较好的区分效果。

| Abstract: | Aspirated and unaspirated are distinctive features of Mandarin speech,but there is no corresponding parameter for digital speech processing.Previous studies have found that an effective parameter cannot be easily extracted using the mel-bank energy to distinguish aspirated and unaspirated consonants.This paper describes a parameter based on the Pseudo Wigner-Ville distribution that was effective in a large corpus containing 212 female and 126 male speakers. |
