Glide insertion to break a hiatus across words in European Portuguese: the role of prosodic, geographic and sociolinguistic factors

Glide insertion to break hiatus has long been reported in the literature to occur in the Northern and Central varieties of Portuguese but this has not been systematically investigated before. From a larger corpus of speech material collected in several locations in the North and Center of Portugal, we selected for analysis a sample coming from six locations in the Northwest of Portugal and one location in the Center. The effects of several linguistic and extralinguistic factors were evaluated, namely, prosodic domain, level of prominence in the second vowel, prosodic status of first some in interaction with others (prosodic domain *region, prominence level*task , prominence level*age). word (W1), region, task, and age. A binary logistic regression model showed that all factors considered are good predictors of the presence of the glide, some considered in isolation (prosodic status of W1 and task), and
