The singing voice is controlled by quite complex physiological mechanisms. Our knowledge in this area is still limited, and much remains to be studied. A fiberscopic view of the larynx and the hypopharyngeal area during singing was recorded on a video system, simultaneously with the acoustic signal. The behavior of the hypopharynx was analyzed in detail by computer, and was related to the acoustic characteristics. It was demonstrated that certain singing skills such as vibrato and trill are closely related to the motion of the hypopharyngeal wall.
