A reversal of the song advantage in vocal pitch imitation

Abstract

Previous experiments have documented an advantage for vocal pitch-matching when participants sing back a short melody, in contrast to when participants attempt to imitate the pitch contour of spoken English. These results appear to confirm recent claims that music involves greater precision of pitch than speech. A re-analysis of these data is reported here that focuses on imitation of pitch trajectories within sung notes or spoken syllables. When analyzed this way, the domain-based difference reverses and speech imitation exhibits an advantage relative to song imitation. These results suggest that domain-specific advantages in imitation vary as a function of timescale.
