A high-resolution glottal pulse tracker

Robert Rodman, David McAllister, Donald Bitzer, D. Chappell

A new method of computing the glottal pulse period of voiced speech is given. This algorithm is based on the mathematically derived fact that the amplitudes of the odd harmonics of a periodic function with period P are zero when the function is expanded in a Fourier series whose coefficients are determined by integrating over 2P instead of the usual P. It is shown that such a glottal pulse tracker is extremely sensitive to sudden short-lived shifts in the apparent frequency of the glottal pulse that circumscribe certain consonants in the speech stream. This method may therefore be used to segment these consonants for various analytical purposes.
