Comparison of manual and automated estimates of subglottal resonances

Wolfgang Wokurek, Andreas Madsack

This study compares manual measurements of the first two subglottal resonances to the results of an automated measurement procedure for the same quantities. We also briefly sketch the sensor prototype that is used for the measurements. The subglottal resonances are presented in the space spanned by the vowelsÂ’ first two formants. A three axis acceleration sensor is gently pressed at the neck of the speaker. In front of the ligamentum conicum, located near the lower end of the larynx, pressure signals may be recorded that follow the subglottal pressure changes at least up to 2 kHz bandwidth. The recordings of the subglottal pressure signals are made simultaneously with recordings of the electroglottogram and the acoustic speech sound with 12 male and 12 female speakers.
