Several investigators have conjectured that the electroglottographic (EGG) wavefonn is inversely proportional to the lateral area of contact of the vocal folds. But this conjecture is essentially impossible to substantiate by observations. We have developed a simple model of the vocal folds that estimates the vocal fold lateral contact area as a function of time. The EGG wavefonn is directly calculated as the, reciprocal of this lateral contact area function. We show how the model may be used to simulate EGG wavefonns for nonnal male voices in model register and vocal fry and for predicting EGG t wavefonns for models of vibrating vocal folds that have a nodule or polyp on one fold.
