Abstract

In this paper, the principle of speech aerodynamics is used, and the acoustic spectrogram and pronunciation airflow waveform are one-to-one corresponded by means of signal processing. The results show that from the airflow waveform, it can be clearly seen that the cooperative pronunciation influence mode between the plosives and vowels /a/ is cis assimilation. The plosives will not only affect the size of vowel airflow and airflow velocity, but also affect the trend of vowel formant. When the aspirated stop is pronounced, the greater the pressure under the glottis results in a longer duration and a higher average airflow velocity, which is about twice as long as the unaspirated stop and more than four times as fast as the unaspirated stop; The stability of the duration of the air flow of the aspirated stop is worse as the voice position is more and more backward, and the stability of the average air flow velocity of the aspirated stop is worse than that of the unaspirated stop.
