Study on Mandarin Voiced Consonant Airflow and Air-pressure Based on PAS6600

摘要

Taking mandarin voiced consonant as its study objects, it has used PAS6600 to collect 3 male and female speakers' articulation signals including speech signal, airflow signal and air-pressure signal in order to explore the mechanism of aerodynamic for mandarin voiced consonant. The study found that: 1) in the process of pronunciation [m] and [n] both in peak expiratory airflow (PEA) and expiratory volume (EV) is less than the [l] and [r], the peak air pressure (PAP) of [m] and [n] is also less than [l] and [n], namely in the process of pronunciation, peak expiratory airflow, expiratory volume, peak air pressure of mandarin voiced consonant nasals is less than the lateral sound and approximant. 2) Mandarin voiced consonant peak air pressure, peak expiratory airflow and expiratory volume of men are more than women, this is due to generally male lung capacity is greater than female. Apart from Expiratory airflow duration (EAD) nasal [n], there is on difference between men and women. Mandarin Chinese voiced consonant airflow pressure study further describes a voiced consonant pronunciation mechanism, to further distinguish the nasal, lateral sound and approximant.
