However, most of these stylization approaches are based on statistical or mathematical properties of the F0 data and ignore the facts of pitch perception. Other types of stylization have been proposed, such as the Momel system (Hirst & Espesser (1993), Hirst, Di Cristo, Espesser (2000). (Institute for Perception Research) in Eindhoven ('t Hart et al. In the '70, pitch contour stylization was introduced as a way to simplify the F0 curve to those aspects which are potentially relevant for speech communication. But it certainly is not the most accurate representation of the intonation contour as it is perceived by human listeners. F0 is an acoustic parameter it provides useful information about the acoustic properties of the speech signal. Many phoneticians use the fundamental frequency (F0) curve to represent pitch contours in speech.
