ABSTRACT:
The invention disclosed herein provides a method and apparatus for analyzing periodic signals so as to determine the degree of harmonicity in real time. Harmonicity estimates are generated for each segment of a signal without the need to process subsequent segments. Harmonicity estimates can be generated in the absence of a fundamental frequency component. The invention has utility in the audio/speech domain for automated speaker identification.
