Vibration of vocal folds is a body-cover layered vibra- tion pattern due to the two-layer tissue structures of vocal folds. A method based on a synchronal imaging system is proposed in order to image and measure the body-cover vibration pattern of vocal folds. This imaging system contains two parts: high-frame- rate ultrasonic imaging part and high-speed video part, which can synchronously image the vibration of the body and cover layers at high speed. Then, image analysis methods are applied to measure the body-cover vibration of vocal folds from both recorded im- age sequences. We analyze characteristics of body-layer vibration based on the measurements from designed experiments. Moreover, these results meet simulations of a body-cover model. Index Terms—Body-cover layers of vocal folds, high-frame- rate ultrasonic (HFRU), high-speed video (HSV), vibration measurement.
