Spectral Measures of Hoarseness in Persons with Hyperfunctional Voice Disorder

摘要

The purpose of the present investigation was to understand the spectral differences between individuals with hyperfunctional voice disorders and subjects with normal voice in terms of H1-H2, H1-A1, H1-A2, and H1-A3 (H1, first harmonic amplitude; H2, second harmonic amplitude; A1, amplitude of the most robust harmonic in the region of first formant frequency; A2, amplitude of the strongest harmonic component in the region of second formant frequency; A3, amplitude of the most robust harmonic component in the region of third formant frequency).
