Phonetic development in late childhood: Longitudinal evidence from Gheg-speaking children

This study is concerned with Albanian children speaking a nonstandard dialect who learn Standard Albanian (SA) in primary school. Our main research question is whether the phonetic characteristics of these children's first dialect are influenced by their learning of SA. We followed longitudinally 48 children in 1st, 2nd, and 5th grades (24 girls, 24 boys, 6-11 years old), some of whom grew up in a village, the others in a city. A picture-naming task was used to record four vowel features of interest, which were analyzed acoustically, then statistically with distributional regression models and generalized additive models. We found evidence that the children's first dialect was affected by SA, suggesting that by 5th grade, they were not fully proficient at distinguishing between the two systems. The four analyzed features followed different developmental trajectories, similar to adults acquiring a second dialect, and similar to feature selectivity observed in language change.
