Journal ArticleDOI
Linear prediction on a warped frequency scale
TL;DR: In this paper, a predictor can be computed from a frequency-warped autocorrelation function obtained from the power spectrum or by a direct linear transformation of the original acf.
Journal Article
Glottal-to-Noise Excitation Ratio - a New Measure for Describing Pathological Voices
TL;DR: The Glottal-to-Noise Excitation Ratio (GNE Ratio) as discussed by the authors is based on the correlation coefficient for Hilbert envelopes of different frequency bands and indicates whether a given voice signal originates from vibrations of the vocal folds or from turbulent noise generated in the vocal tract and is related to (but not a direct measure of) breathiness.
Journal ArticleDOI
Selection and combination of acoustic features for the description of pathologic voices
TL;DR: The glottal to noise excitation ratio (GNE) is an acoustic measure designed to assess the amount of noise in a pulse train generated by the oscillation of the vocal folds that is found to be independent of variations of fundamental frequency and amplitude.
Journal ArticleDOI
Determination of the instant of glottal closure from the speech wave
TL;DR: The determinant method seems to be very reliable even for otherwise difficult cases, such as the vowel /u/ and the inversely filtered waveforms and the formants obtained from predictors determined on a shifted interval.
Journal ArticleDOI
Acoustic voice analysis by means of the hoarseness diagram.
TL;DR: The hoarseness diagram and its underlying algorithms are shown to constitute a useful approach to acoustic voice analysis in research and clinical practice and demonstrate several application possibilities, including the quantitative monitoring of individual voices.
