Section Introduction. Recent Approaches to Modeling the Glottal Source for TTS
One of the most important discoveries in speech science was the finding that voiced speech, which accounts for the major part of most utterances, could be fairly well modeled by a pulsive source function serving as excitation for an all-pole transfer function. The source function represents airflow through the glottis, and the transfer function captures the filtering effect of the vocal tract.
