Abstract
Interpretation of the electroglottographic (EGG) signal involves at least two major stages of investigation, the transduction stage and the modeling stage. This article addresses some aspects of both of these stages. In the transduction stage, it is shown how electrode size and orientation can affect the signal-to-noise ratio and the linearity of the EGG signal. Best results are predicted when interelectrode distance is small, electrode size is on the order of the glottal length, and the electrode angle is small. In the modeling stage, it is shown that pulse widening of the EGG waveshape results from increased adduction, that peak skewing results from glottal convergence (in the presence of vertical phasing), the knee in the EGG waveform results from medial surface bulging, and gradual sloping of the waveform (toward a triangular shape) results from increased vertical phasing.
