Asymmetries between Perception and Production.
Pitch and Length in two varieties of Italian (Pisan and Crotonese)
this paper, original experimental data on the perception of length and pitch
by Italian listeners are presented in order to investigate the relevance of
native language in the perception of Pisan and Crotonese pitch and duration. Acoustic stimuli relative
to the two local varieties of Italian were modified in relation to vowel
duration and F0 and then judged via an ABX discrimination test by Pisans, Crotonians and a
control group. Prominent vowels in Pisan are
consistently modulated, while in Crotonese,
duration is used to express prominence. However, in both varieties the two
prosodic features are not phonologically distinctive.
results obtained indicate that all listeners are equally sensitive to pitch
and duration. Listeners show no significant preference for their native
varieties or for the prosodic feature specific of their own variety, thus
suggesting that when not phonologically distinctive, these prosodic features
do not influence perception.
variable of music training is also
taken into account, confirming the previous finding of the relevance of a
musical education in perceptive tasks involving acoustic parameters, even in
