Repeated Vowels in Italian: An exploratory study

This paper addresses the articulatory realization of repeated identical vowels in Italian, such as they exist in root-internal position (e.g. coorte ‘cohort’, Sahara ‘id.’) or across a morpheme boundary (atee ‘atheists.f’, coordinare ‘to coordinate’). In structural terms, these vowel sequences give rise to a hiatus, but their actual realization is variable. At fast speech rate, they may collapse into a single vowel also in terms of total duration. In careful speech, however, they retain a much longer duration than their single vowel counterparts (cf. corte ‘court’, Sara ‘id.’). In addition, and crucially for our purpose, they may exhibit some hints at rearticulation at the boundary between the first and the second vowel. Some evidence that this may indeed occur was found by means of the UTI technique in a corpus of carefully produced speech.
