“…Unfortunately, a study examining the correlation between 19 common acoustic measures and a clinician-based perceptual voice assessment protocol, the Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) scale, found that no acoustic measure was well-correlated with strain (Bhuta, Patrick, & Garnett, 2004). More recently, the perception of strain has been shown to have strong relationship with cepstral measures and moderate relationship with spectral measures in a group of dysphonic speakers with predominately strained voice quality (Lowell, Kelley, Awan, Colton, & Chan, 2012). However, when the primary factor of the cepstral measure – cepstral peak prominence -- was examined in a group of individuals with nonhomogeous diagnoses, no significant correlation was found between cepstral peak prominence and the perception of strain (Brinca, Batista, Tavares, Gonçalves, & Moreno, 2014).…”
