Abstract

An automatic image processing method is proposed to extract vocal fold vibrations from high-speed digital imaging. Extracted regular vocal fold vibrations contribute to periodic voices, and irregular vocal fold vibrations contribute to aperiodic voices. The effects of image resolutions are investigated. This study combines the features of both image and voice signal processing and provides a valuable automatic image processing technique for the measurement and quantification of voice productions from high-speed imaging.
