Abstract
Experimental phonetics development to today has undergone a long and complicated process. The field of study from the acoustic analysis of expansion to the physiological and perceptual field. Speech aerodynamics signal is one of the most important physiological signal language research, plays an important role in human phonation process. Air pressure signal as an important physiological signal, which has great significance to the study of speech physiology, mainly through speech aerodynamics equipment acquisition. In this paper, according to the need of research, established by MATLAB program analysis platform, can be edited on the speech, the airflow and pressure signal is better, which is more suitable for speech research.
