Performance of the phonatory deviation diagram in the evaluation of rough and breathy synthesized voices

Abstract: The normality area and the phonatory deviation diagram quadrant can discriminate healthy voices from rough and breathy ones. Voices with higher degrees of roughness and breathiness are proportionally located outside the area of normality, in the lower right quadrant and with concentrated density.

“…Higher values of degrees of roughness and breathiness in types III and IV signals in relation to type I and type II signals are justified by the fact that these two perceptual parameters are associated in general with an increase in the irregularity and noise components in the signal, respectively (11)(12)(13)(14)(15)(16) .…”

“…As previously mentioned, PDD was extracted from the vowel /ε/ records edited and recorded in Voxmetria. PDD analyzes noise and perturbation parameters in combination, based on four acoustic measures: jitter, shimmer, correlation, and GNE (13,15,16) . Jitter assesses instabilities in standard vocal fold oscillation, quantifying frequency variations cycle by cycle, while shimmer quantifies changes in the phonatory cycle amplitude (21) .…”

“…The shapes were also classified by using the 10-cm ruler. Lastly, PDD was divided into four equal quadrants for distribution into lower-left (1), lower-right (2), upper-right (3), and upper-left (4) (Figure 2) (13,15,16) .…”

“…Other studies (9,12) have shown that a vocal alteration leads to multiple manifestations, either at the glottic and/or filter level. There is a larger number of studies investigating acoustic measurements related to the glottal source, such as disturbance and noise measurements (13)(14)(15) , as they are more related to auditory perceived vocal deviation. However, the impact of voice disorders on vowel distinctiveness and its effects on verbal message transmission needs to be studied, considering that this finding can elucidate and reinforce the understanding of the communicative limitations of this kind of disorder.…”
