Abstract
<h2>Summary</h2> A noninvasive pressure-flow technique was used to assess laryngeal airway resistance (R<sub>law</sub>) in eight young adult women and seven men. Syllable structures used were consonant-vowel (/pi/) and consonant-vowel-consonant (/bip/). The data were obtained from oscillographic records of intraoral air pressure and transglottal airflow over 2 consecutive days. Repetitions of each syllable context were produced at each subject's 25th, 50th, and 75th percentiles of vocal sound pressure level. No significant differences in R<sub>law</sub> were found across days for the two groups. Women had significantly greater R<sub>law</sub> than did men for the /pi/ and /bip/ contexts. Men showed a significantly greater average airflow rate than did women for both syllable contexts. Airflow, air pressure, and the ratio R<sub>law</sub> increased as the sound pressure level of voice increased. The technique appears to be useful for characterizing certain features of laryngeal airway resistance for men and women.
