Azpeitiko azentuaren gauzatze fonetikoaz

Abstract

Lan honetan, Azpeitiko hizkeraren azentuaren ezaugarri akustikoak aztertzen ditugu. Singular/plural hitz pareak erabili ditugu bokal azentudunen eta azentugabeen arteko diferentzia akustikoak miatzeko. Emaitzek erakusten dute tonuak eta intentsitateak azentu-gunea adierazten dutela. Bereziki, aztertu dugun testuinguruan, silaba azentudunek tonu gorakada erakusten dute. Iraupena, alderantziz, ez da erabiltzen azentuaren ezaugarri esanguratsu bezala. Emaitza hauek beste euskal hizkera batzuen datuekin konparatzen ditugu eta iraupenaren azentuzko erabilerak bokalen galera gertakarietan izan dezakeen eragina kontsideratzen dugu. We report on an experiment on the acoustic cues of stress in the Basque variety of Azpeitia. We use singular/plural minimal pairs to examine acoustic differences between stressed and unstressed vowels. Both pitch and intensity appear to cue lexical stress. In particular, in the context that we have examined, stressed syllables show a pitch rise. On the other hand, we did not find a significant effect of vowel duration as a cue to stress. We compare these results with work on other Basque dialects and offer some speculation on the relationship between the role of duration as a cue to stress and phenomena of vowel deletion.
