Perception and production of Italian vowels: an ERP study
نویسندگان
چکیده
In the present study, cortical responses of two sustained Italian vowels, /a/ and /i/, were analyzed in perception and production tasks by using the event-related potential (ERP) technique. First, we showed that the earlier auditory waveform complex, N1/P2, was elicited in both experimental tasks by acoustically presented vowels. More interestingly, the cortical activity of auditory cortex seems to reflect different spectro-acoustical items of Italian vowels in the production task. Specifically, the vowel /a/ generated a weaker activity than /i/ as revealed by different neuronal modulations; moreover, during speech production, the auditory cortex showed a dampening and delaying of its activity in the left hemisphere.

Objective: One of the parameters showing the correct phonetic and phonological development is the correct and clear articulation of vowels is achieved by changing the shape of vocal cords through altering the height and position of the tongue and the movement of the lips and jaw. The tongue’s height and position are the basis of the production and difference of vowels. In other words, the raw s...
