Abstract :
A new representation of glottal-edge data derivable from high-speed laryngeal films is given. The resulting simple curves represent the glottal shape during phonation and are so arranged that various one-and two-dimensional discrete Fourier transforms can be used to test glottal symmetry and vocal fold vibration rates and phases. Possible discriminant features are suggested and illustrated.
