Acoustic descriptors of emotional voice quality have traditionally been provided in terms of fundamental frequency (f0), amplitude and duration. These cues have formed the basis for numerous studies of the emotional content of voice signals. The present work examines additional factors that arise as a result of the underlying production mechanism. Specifically glottal characteristics of different emotionally styled voice types are examined using the electroglottogram signal. This preliminary study, using a single speaker, investigates a number of electroglottogram measures relating to closed quotient (closed time of the glottis/cycle length) and rate of contact at closure and opening for the sustained vowel /a/, produced when simulating the emotional states sad, tender, neutral, joy and anger. The results suggest that differences exist in terms of glottal attributes for a particular emotion.
