Earlier attempts to establish LTAS criteria to quantify pathological voice qualities in
dysphonic patients have mainly centered on organic voice disorders or qualities signalling …

Diagnostic evaluations of patients with voice disorders have always required a
multidimensional approach–including a medical examination of the voice generating …

Long-term-average spectrum (LTAS) is an efficient method for voice analysis, revealing both
voice source and formant characteristics. However, the LTAS contour is non-uniformly …

Within this study a retrospective analysis of clinical voice perturbation measures, Dysphonia
Severity Index and subjective perceived hoarseness was performed to determine their value …

This paper evaluates the capabilities of the Glottal to Noise Excitation Ratio for the screening
of voice disorders. A lot of effort has been made using this parameter to evaluate voice …

The paper investigates the acoustic measures of pitch perturbations and vocal noise in
pathological voice signals in terms of their ability to discriminate between normal and …

In order to develop an assessment system for voice quality to be used in voice clinics,
acoustic measures of “roughness” in pathological voices were investigated. The extracted …

The perceptual GRBAS scale for deviant voice quality (completed with a" I" parameter:
Instability= fluctuation of voice quality over time) was tested in 5 different institutes on 943 …

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. So far its …
