The response of the vibratory pattern of the vocal folds to externally induced changes of supraglottal pressure was measured. Tracings of the variation of Fo after a step change in pressure indicated that a C pressure variation similar to a single bipolar cycle of an 8-10 Hz sinusoid is fast enough to vary the average transglottal and/or intraglottal pressure without stimulating compensatory action during the induced pressure pulse and slow enough to allow the vocal fold oscillatory behavior to respond to the change in pressure during each half of the pulse. An example is presented of the shape of the glottal airflow pulse during a continuous 10 Hz sinusoidal induced pressure variation, as derived by inverse filtering oral airflow.
