Airflow Acoustic Research on Mandarin Voiceless Fricatives

Abstract

Taking Chinese mandarin voiceless fricatives as its research objects, this paper has collected the airflow signals from 20 speakers (10 males and 10 females) with PAS6600 to collect the speech, airflow and air-pressure signals, studying on the Peak Air Pressure (PAP), Peak Expiratory Airflow(PEA), Expiratory Volume(EV) of the Chinese mandarin voiceless fricatives.Among the fricatives, [f], [s], [x] and [sh], their AP values are higher because of their voiced degrees.But [h] its PEA and EV values are higher because of its lower voiced degree.
