Title
Synthesizing the motion of the vocal folds using optical flow based techniques.
Abstract
Different playbacks have been proposed to synthesize the dynamical information of the vocal folds. However most of them rely on the delineation of the glottal gap using segmentation techniques which is a complex task and usually requires a manual supervision. In order to solve this issue, three new playbacks based on the optical flow computation are presented. Two of them, called Optical Flow Glottovibrogram and Glottal Optical Flow Waveform, analyze the global dynamics; and the remaining one, called Optical Flow Kymogram, analyzes the local dynamics. The reliability of the proposed playbacks is evaluated by comparison with traditional representations, showing a great correlation in shape with the traditional playbacks, and allowing the identification of the most important instants of time, such as closed-states and maximal opening. In addition, they provide complementary information to the common spatio-temporal representations, although the new playbacks are lightly blurred. (C) 2017 Elsevier Ltd. All rights reserved.
