Buldialect - Measuring Linguistic Unity and Diversity in Europe (2006-2010) was a joint project between the University of Tübingen, University of Groningen and Bulgarian Academy of Sciences sponsored by the Volkswagen Stiftung. The aim of this project was to a) create Bulgarian phonetic and lexical digital dialect data base; b) analyze the data using the existing statistical methods from dialectometry and compare it to the traditional scholarship; c) develop new quantitative methods that can be used to analyze dialect and language data. During the project, pronunciations variants of 156 words from 197 villages in Bulgarian were compiled and digitalized. Lexical data base consist of lexical varaints of 110 words collected from the same set of villages. The results of applying different quantitative techniques, both the old ones and those developed during the course of this project, to the Bulgarian pronunciation data have shown that some of the traditional divisions of this area have to be questioned and that they were not based purely on the linguistic criteria.

Manually corrected multiple string aligned Buldialect data (IPA transcribed) that consists of the phonetic variants of 152 words collected at 197 sites and annotated for various linguistic phenomena like metathesis, phonetic mergers and splitters, is available in Data Packages format. This data is suitable both for (geo)linguistic analyses and testing of the alignment algorithms. To obtain the data in this format, please send an e-mail to jelena dot prokic at gmail dot com.
Subset of the Buldialect data specifically designed for testing of the alignment algorithms is part f the BDPA database and can be found here.
