Influências do polonês sobre a produção de /l/ pós-vocálico: dados dos Rio Grande do Sul e do Paraná.

This research analyzes the productions of post-vocalic /l/ in Brazilian Portuguese realized by bilingual speakers of communities which use Polish as an immigrant language. The data -- collected from a bilingual speaker from the city of Araucária -- were compared with the results from Vieira (2019), whose productions were made by bilingual speakers from the city of Dom Feliciano. To characterize the productions, data were submitted to acoustic analysis, aiming to observe the lateral velarization degree according to Narayanan et al. (1997), Recasens et al. (1995), Recasens (2004) and Brod (2014). In each production, we measured the values of F1 and F2 and the average of the difference between F1 and F2, which is the parameter to determine the velarization degree of /l/. The analyses indicated that the productions of the subject from Araucária were characterized by a high velarization degree and, in some cases, by vocalization. In this way, being less velarized (more frontal), they differ from the productions observed in the speech of subjects from Dom Feliciano who used Polish with a similar frequency and at the same living spaces -- the family space. The productions of the subjects from Dom Feliciano also consider velarized /l/ realizations, however, these productions often emerge from the speech of subjects who are frequently exposed to spaces in which Polish is not used. Another aspect revealed in lateral productions made by the subject from Araucária is related to the vocalic context influence, with less velarized /l/ productions following front vowels. In preliminary analysis, therefore, the results indicate phoneticphonological differences between the post-vocalic /l/ productions of the two communities influenced by Polish as an immigrant language.
