Abstract

On basis of MATLAB programming language, this paper adopts the method of experimental phonetics, in mandarin Chinese plosive (pa) as the research object, with 20 pronunciation (10 male female) corpus as experimental basis, designs and implements the breathing air flow signal and pressure signal analysis program, through the same gender painted the same signal is fold, including air flow signals mainly focus on left side, about air pressure signal is divided into two parts, further draw a picture of each type of signal average chart.The average graph of each part was used to find 20 points to match the curve. The least square fitting of the line (polynomial fifth-order fitting) and sin function were used to fit the curve respectively, to establish the flow and pressure model of stop [pa]. Through analysis and comparison, the polynomial fifth-order fitting model was selected as the optimal fitting model.
