The use of digital methods to identify the structural and territorial units of the central-southern dialect of the Udmurt language based on the analysis of field records

The article presents the results of computer phonetic-etymological and glottochronological analysis of data from the dialect of the village of Bobya-Ucha, Malopurginsky District, Udmurt Republic. As far as we know, the dialectal peculiarities of the studied material have not previously attracted the attention of researchers. In the course of work under the RSF grant, audio recordings of two dictionaries of the colloquial language were collected. The vocabulary of which is still used in everyday life. At the present days, the audio materials of the dictionaries were transcribed and placed on the LingvoDoc platform (lingvodoc.ispras.ru), which made it possible to establish etymological links with the basic dictionaries of Udmurt dialects. Then, with the help of special programs, the divergence of the Bobya-Ucha dialect from the Udmurt literary language was analyzed. The phonetic peculiarities of the studied dialect were revealed and its dialectal affiliation was clarified. The comparative-historical analysis of phonetic peculiarities has shown that the consonant phonemes of the studied dialect have not undergone any changes and have no dialectal peculiarities. However, there is a specific sound ’ in the Bobya-Ucha dialect, the study of which requires further research. The vocalic system of the studied vernacular is determined by several changes in the acoustic and articulatory properties of individual phonemes: *ɪ̈ > ə, *ɐ > ə, *ɞ > ɜ. Thus, based on the etymological-phonetic and glottochronological analysis (96% coincidence), we can see that the dialect of the village Bobya-Ucha belongs to the central-southern dialect of the Udmurt language.
