%X Current high-speed videoendoscopy (HSV) make it possible to obtain 4000 images of the larynx per second. By this process, the analysis of the vocal folds can provide significant information. This is also possible to estimate the area of the glottis. All this information is useful for the study of the various phonatory modes, but also for glottal flow estimation which allows the improvement of our acoustic understanding of speech signals. For the usual modes then for other particular phonatory situations, we present a comparison of various speech signals: acoustic, Electro-Glotto-Graphic, glottal area, and estimation of the glottal flow by inversion of the vocal tract.
