Abstract

The use of high-speed videoendoscopy (HSV) in combination with image-processing techniques is the most promising approach to investigate vocal-folds vibration and laryngeal dynamics in speech and singing. The current challenge is to pro- vide facilitative and informative playbacks for clinical and research purposes. We present three new facilitative playbacks using an optical-flow framework (OF), which has the main advantage of requiring no glottis segmentation. The method has been tested on a database of 60 HSV sequences, which covers different voice qualities for spoken and sung vowels. The new data representations have been compared with commonly used facilitative playbacks.
