We present a non-invasive attempt to indirectly measure the subglottal sound pressure. This quantity opens an additional acoustical path to observe the voiced sound source. The subglottal sound pressure contours of two phonation qualities, the modal phonation quality and the breathy phonation quality, are compared. The electroglottographic signal was recorded simultaneously as a well known reference basis for physiological details of voice production.
