My PhD thesis (Le affricate dentali nell’italiano di Bolzano. Un approccio sociofonetico /Dental affricates in the Italian of Bolzano. A sociophonetic approach) represents a very first enquiry on the Italian variety spoken in Bolzano (South Tyrol). The object of the research is very peculiar from a sociolinguistic point of view. Firstly, Italian speakers in Bolzano represents the majority linguistic group, whereas in South Tyrol the most widespread language is German. Secondly, Italian speakers came in Bolzano during the last century from different areas of Italy, thus resulting in a lack of a common dialectal background.
It is interesting to note that no previous study has provided a data-driven definition of the Italian spoken in Bolzano, and the literature in this respect is very poor and conflicting. For this reason, one of main purpose of this thesis was the collection of a huge corpus of spoken Italian of Bolzano, apt for future researches. Then, a sociophonetic approach to the data was preferred, since it allows to see the complex relations among different linguistic and social variables (Foulkes et al. 2010: 704).
Our data consist of 42h 43’ recordings with 42 Italian speakers of different ages, sexes, degrees of education and districts of residence. Each speaker was engaged in a conversation with the researcher, in which it was collected a more semi-spontaneous variety of speech (cfr. Labov 1994). Then, speakers were asked to read a long wordlist consisting of 310 isolated real words presented in isolation on a computer screen, and finally to read 9 tongue-twisters. Among the 310 words there were 68 instances of a dental affricate in different phonological constraints. Each instance was then isolated, and annotated in PRAAT following a specific annotation protocol which has been developed for this analysis.
The analysis focused on three main linguistic parameters: sonority degree, duration, and place of articulation. We tested the distribution of each linguistic parameter
The inspection of the spectrograms has revealed that it exists a sort of intermediate degree between voiced and voiceless dental affricates: in these realizations, which we called intermediate, the occlusive part of the dental affricate presents the typical sonority band, whereas sonority disappears in the following fricative part. Affricates sometimes present a gap between the occlusive and the fricative part, that has been named “post-burst aperiodicity”, following Foulkes & Docherty (2011).
The sociophonetic analysis via SPSS has shown that intermediate voicing characterizes the speech of old and uneducated speakers, but it’s however well attested also in young speakers with low degree of mobility outside the town of Bolzano. Moreover, intermediate voiced affricates occur more frequently in the post-nasal and post-lateral context, which is highly variable throughout Italian regional dialects. On the contrary, the post-burst aperiodicity is more frequently found in speakers with a high degree contact with the German inhabitants of the area, and it characterizes the speech of young, educated men and women.
These data has led to the conclusion that a process of koineization is on-going in the Italian of Bolzano. Following Kerswill & Trudgill, it may be said that the Italian of Bolzano is nowadays levelling the more marked differences in pronunciation, and starting a process of focusing. The emergence of an intermediate degree of sonority in a high-variable phonotactic context has to be interpreted in this way. Moreover, language contact with German might be playing a role in the younger generations, but it doesn’t seem to generally affect the new dialect under formation.
