【 摘 要 】
The human voice is produced by self-sustained oscillations of vocal folds and the resulting pulsating jet flow passing through the glottis. To mimic this sound generation mechanism, many vocal fold models have been proposed and developed for many years. The first well-known vocal fold replica, comprised of a reed and its retainer, was proposed by von Kempelen around 1780 for his speaking machine [1]. This reed-type artificial vocal fold has been still used because of its easy fabrication geometry [2]. By fabricating it with the vocal tract model of a simple tube with a cylindrical constriction, formant peaks appear in the spectrum of the generated sound like the human vowel production.
