    Abstract

    This paper investigates the use of Instantaneous Frequency Distributions for the analysis of Speech and Audio signals. In particular, methods are proposed for fundamental frequency determination of speech and audio, and method for the tracking of resonances, or formants in the case of speech, present in a signal is described. The techniques considered that are applied to the Instantaneous Frequency Distribution of the signal in order to extract a desired feature or features specifically involve the use of dynamic programming in order to produce smooth estimates.
