The purpose of this study was to compare mean oral pressure (P(o)) and P(o) variability: (1) between tracheoesophageal (TE) and laryngeal speakers, and (2) between TE speakers' voiced and voiceless phonemes. Sixteen TE and 10 laryngeal speakers produced stops and fricatives in a phrase while P(o) was recorded. The TE group produced greater mean P(o) and P(o) variability than the control group. TE speakers did maintain a P(o) difference between cognate members with greater pressure on voiceless consonants. A number of possible explanations for the findings are reviewed, although clearer delineation of the issue will require further study.
本研究的目的是比较平均口腔压力（P(o)）和P(o)变异性：（1）在气管食管（TE）发音者和喉发音者之间；（2）在TE发音者的有声和无声音素之间。16名TE发音者和10名喉发音者在说出一个短语时发出塞音和擦音，同时记录P(o)。TE组产生的平均P(o)和P(o)变异性均高于对照组。TE发音者在同源音素之间确实保持了P(o)差异，无声辅音的压力更大。尽管需要进一步研究才能更清楚地界定这个问题，但我们对这些发现的一些可能解释进行了综述。
