Fundamental frequency (f0) stability is generally assumed to be an attribute of the singing voice, though it can also found in speech. In a previous work, was that sung sentences performed with relative freedom within MPB (Musica Popular Brasileira) style show less f0 variability comparison their spoken counterparts and, for this reason, we account important acoustic feature distinguishes from The current study complementary whose results statistically confirmed hypothesis has more stable than Our aim perpetual experiment verify whether perceived by naïve listeners. 36 listeners were asked classify actresses and singers four available answers, choosing only one them. dataset used perceptual stimuli formed textual units comprising 25 uttered respectively actress singer representative part full dataset. Listeners' classification obtained each sentence compared variation same sentence. Statistical analysis done means discrete choice model (DCM) aiming variance could choose between responses. result indicates significant (Pr (> |z| 2.22e-16) relationship classification. discussion takes listeners' impressions about test conclusion finding empirical evidence cognitive aspects music.
