Combining Regular Sound Correspondences and Geographic Spread

Abstract

In this paper we combine the geographic variation of closely related language variants (‘dialects’) with the distribution of sound correspondences through the lexicon. One of the central problems with sound correspondences at the dialect level is that they are not very regular, especially when they are investigated in sufficient detail. Sound changes spread both through a language (e.g., from one word to another) and through the population of speakers (in our case through a population of villages with different dialects). Both processes happen at the same time, and the challenge is to reconstruct what has happened from a snapshot of synchronic data. The method described in this paper allows us to track the geographic spread of sound changes and the underlying patterns of linguistic diversity simultaneously. By combining the two, it is possible to detect areas of intensive linguistic contact and gain better insight into the mechanisms of language change.

Regional variation in Kurmanji: A preliminary classification of dialects

“…Consonants, on the other hand, are relatively stable across related dialects, as Prokić (2010) also confirms. Again in keeping with what is known about comparisons of closely-related varieties, we find that there are relatively few stable and consistent sound correspondences (Prokić and Cysouw, 2013), and most of them concern vowels. Table 3 provides a selection of the correspondences that can be observed.…”

Unsupervised Learning of Cross-Lingual Symbol Embeddings Without Parallel Data

“…Discovered correspondences may also be able to tell us about typology in themselves. For example, some measures of orthographic difference and sound correspondences correlate with geographic factors in language development (Heeringa et al, 2013;Prokić and Cysouw, 2013). Discovered strong symbol correspondences (especially if the method is applied to phonetic sequences) could also be of typological interest in themselves.…”
