The study was done on 4 french speaking subjects: 2 men and 2 women. The pulmonary flow and volumes, aesophageal pressure and electromyography by needle of an internal intercostal were simultaneously recorded during normal and whispered pronounciation of 48 syllables These were made up of an occlusive consonant in a first position or not, followed by the vowel "A". The pneumotachographic tracing is reproducible both in normal and whispered voice, differing according to the mode of pronounciation. The aesophageal pressure and the electromyography of the internal intercostal are equally different. The comparative study of the ventilatory function in normal and whispered voices enabled the dissociation on pneumotachographic tracing of the variation of flow due to movements of the naso-bucco-pharyngeal articulations from those coming from movements of the vocal cords.
该研究针对4名说法语的受试者进行：2名男性和2名女性。在正常和轻声发出48个音节的过程中，同时记录了肺流量和容积、食管压力以及肋间内肌的针电极肌电图。这些音节由处于首位或非首位的闭塞辅音，后面跟着元音“A”组成。呼吸流速描记图在正常语音和轻声语音中均可重现，根据发音方式而有所不同。食管压力和肋间内肌的肌电图也同样不同。对正常语音和轻声语音中的通气功能进行比较研究，能够在呼吸流速描记图上区分出由于鼻-颊-咽关节运动引起的流量变化与声带运动引起的流量变化。
