Akustičke karakteristike samoglasnika /o/ kod govornika sa područja kosovsko-resavske dijalekatske zone

Abstract

The study looks into spectral characteristics of the vowel /o/ in spontaneous speech of 10 male speakers of Kosovo-Resavian dialect. Previous dialectological research on Kosovo-Resavian reported on a more open realization of /ŏ/ (Okuka 2008: 200), which is why this variant is commonly described as a regional marker (Sudimac 2016: 574). Discussion questions were used as the research instrument in order to collect the data for spoken corpus. The recorded material was processed using Praat, version 6.2.13 (Boersma, Weenink 2022). Words containing long and short realizations of the stressed vowel /o/ were observed in voiced and voiceless phonetic environments, and the first three formants (F1, F2, F3) were measured alongside vowel duration. The statistical analysis of the acoustic measurements was generated in R, version 4.2.1. The results indicate that, in the spontaneous speech of our participants, there are no significant durational differences between the long /o/ vowel and its short counterpart, neither in voiced nor voiceless contexts. The results also suggest that there is a notable quality difference between the two variants with regard to the tongue height, whereas the differences in centralization did not prove to be significant. Therefore, the obtained results are essentially different from those reported in some previous studies on Kosovo-Resavian vowels in careful, i.e. elicited speech, which seems to suggest that there is a difference in the way vocalic quality is realized across various speech styles.
