Parametric analysis of aspirated and unaspirated Mandarin consonants

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.
