Energy harmonics
WebIn the present study acoustic analysis of sustained vowels is considered. A simplek-means nearest neighbor classifier is designed to test the efficacy of a harmonics-to-noise ratio (HNR) measure and the critical-band energy spectrum of the voiced speech signal as tools for the detection of laryngeal pathologies.
