“…A benefit of this particular model was the opportunity to vary one feature at a time, teasing apart the impact of incomplete glottal closure from altered subglottal pressure, amplitude of vibration, mucosal wave, symmetry, and regularity. It is likely that the ambiguous relationship between gap size and breathiness in human subjects (e.g., Rammage et al, 1992) occurs because gap size is not the only feature differing among study participants.…”

Purpose To determine 1) how specific vocal fold structural and vibratory features relate to breathy voice quality and 2) the relation of perceived breathiness to four acoustic correlates of breathiness. Method A computational, kinematic model of the vocal fold medial surfaces was used to specify features of vocal fold structure and vibration in a manner consistent with breathy voice. Four model parameters were altered: vocal process separation, surface bulging, vibratory nodal point, and epilaryngeal constriction. Twelve naïve listeners rated breathiness of 364 samples relative to a reference. The degree of breathiness was then compared to 1) the underlying kinematic profile and 2) four acoustic measures: cepstral peak prominence (CPP), harmonics-to-noise ratio, and two measures of spectral slope. Results Vocal process separation alone accounted for 61.4% of the variance in perceptual rating. Adding nodal point ratio and bulging to the equation increased the explained variance to 88.7%. The acoustic measure CPP accounted for 86.7% of the variance in perceived breathiness, and explained variance increased to 92.6% with the addition of one spectral slope measure. Conclusions Breathiness ratings were best explained kinematically by the degree of vocal process separation and acoustically by CPP.

“…Though correlation between the size of the glottal gap and breathiness is not always high (Södersten & Lindestad, 1990; Rammage, 1992), increasing vocal process separation, parameterized by ξ 02 , caused decreasing CPP in SS11 and is expected to increase perceived breathiness.…”

“…Some of its attractiveness stems from the idea that they might supply a way to quantitatively assess voice characteristics that are otherwise difficult to measure ͑e.g., Kreiman and Gerratt, 1996͒. Studies on pathological voices have correlated acoustic features with perceptual qualities ͑Murry et al., 1977;Hammarberg et al, 1980Hammarberg et al, , 1981Fritzell et al, 1983a;Askenfelt and Hammarberg, 1986;Hirano et al, 1986Hirano et al, , 1988Eskenazi et al, 1990;Rammage et al, 1992;Kreiman et al, 1992;Kreiman and Gerratt, 1994;Dejonckere, 1995;de Krom, 1995;Bielamowicz et al, 1996;Hillenbrand and Houde, 1996͒ or, to a lesser extent, with physiologic conditions at the glottis ͑Hirano et Rammage et al, 1992͒. However, the results are often ambiguous, and sometimes even contradictory, so the choice of the appropriate acoustic measures as well as their interpretation are still unsolved problems.…”

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 properties have only been studied for synthesized signals, where it was found to be independent of variations of fundamental frequency (jitter) and amplitude (shimmer). On the other hand, other features designed for the same purpose like NNE (normalized noise energy) or CHNR (cepstrum based harmonics-to-noise ratio) did not show this independence. This advantage of the GNE over NNE and CHNR, as well as its general applicability in voice quality assessment, is now tested for real speech using a large group of pathologic voices (n = 447). A set of four acoustic features is extracted from a total of 22 mostly well-known acoustic voice quality measures by correlation analysis, mutual information analysis, and principal components analysis. Three of these measures are chosen to assess primarily different aspects of signal aperiodicity, while the fourth one indicates the noise content of the signal. All analysis methods lead to the same feature set that consists of a measure of period correlation, jitter, shimmer, and GNE. The two-dimensional projection of this set named "hoarseness diagram" allows a graphical illustration of voice quality that can be easily interpreted.

“…This material has a number of practical advantages. Production of an isolated vowel, especially vowels such as /a/ [16], is not affected by articulation factors. Stabilized isolated vowels have also been shown to be useful for objective voice evaluation of frequency and intensity stability (jitter and shimmer) and glottal closure (phonatory airflow) [17].…”

Choice of voice sample material can influence perceptual judgments by a jury. The twofold purpose of this study was first to validate the pertinence of a sustained vowel for perceptual voice analysis in French speakers and second to test the hypothesis that use of only the stabilized portion of the vowel would lead to underestimation of dysphonia. Voice samples were recorded in 60 dysphonic patients and 20 normal controls. Three different sample materials were obtained for each subject, i.e. connected speech, a sustained vowel including both the initial and stable portion (complete sustained vowel), and a sustained vowel including only the stable portion (stabilized sustained vowel). The jury was composed of 7 experienced listeners. Jury consistency was measured as a percentage of agreeing judgments for the same subject. No difference in consistency was observed using the three sample materials. Judgments on stabilized sustained vowels were confirmed as less severe than judgments on connected speech. Judgments on complete sustained vowels were comparable to judgments on connected speech.
