Auditory Perception of Impulsiveness and Tonality in Vocal Fry

Vocal fry is a voice quality that occurs in healthy voice, but it can also be sign of disorder. In this study, we investigated the relationship between parameters production, dedicated psychoacoustic feature, and perceptual aspects vocal fry. Two experiments were carried out to determine whether fundamental frequency, open quotient, glottal area pulse skewness affect perception synthetic vowels. Thirteen listeners participated assess following attributes: binary (yes/no) impulsiveness, tonality, naturalness (7-point Likert scales). The results suggest mainly triggered by low quotient plays role, with narrower pulses slightly increasing probability perceived Perceived tonality inversely related impulsiveness. Internal reference standards appear have fixed elements may affected anchoring short-term (i.e., within-vowel) context stimuli. addition, prominence peaks observed loudness curve over time appears graduations
