- This paper mainly selects three teenagers aged 15-17 as research subjects.Study the various parameters of the airflow and air pressure during the obstruction and de-blocking phases of the aspirated stops and non-aspirated stops of this age group.It mainly collects the expiratory airflow duration,peak air pressure,expiratory volume,peak expiratory airflow to compare the aspirated and non-aspirated stops at different articulations.The results show that (1) the obstruction phase: the duration of the aspiration stops of the same place of articulation is longer than the duration of the non-aspirated stops ;the duration of the obstruction of the lip and the tip of the tongue is greater than the duration of the obstruction of the tongue;the air pressure value of the aspirated stops is slightly higher than the non-aspirated stops.(2) De-blocking stage: The expiratory airflow duration, expiratory volume,peak expiratory airflow of the aspiration stops are larger than the non-aspirated stops , and the expiratory airflow duration is proportional to the peak airflow and expiratory volume.
