本文通过模拟普通话舌尖前、舌尖后、舌面前三组辅音气流通道的方式进行语音实验,就气流通道长度对舌尖前、舌尖后、舌面前这三组辅音音质的影响进行了实验验证,得出气流通道长度对舌尖前、舌尖后、舌面前及舌叶音这三组辅音的发音有较大影响,而气流通道的宽窄及形状则对音色影响不大的结论。 In this paper, the speech experiment was conducted by simulating the three consonant airflow channels in the front of the tongue, the tongue, and the lingual face, and the effect of airflow channel length on the three consonant sound quality before tongue tip, tongue tip and tongue surface was tested. The length of the airflow channel has a significant effect on the pronunciation of the three consonants before the tip of the tongue, behind the tongue, behind the tongue and before the tongue, and the width and shape of the airflow channel have little effect on the tone.
