Dialect groupings can be discovered ob- jectively and automatically by cluster analysis of phonetic transcriptions such as those found in a linguistic atlas. The first step in the analysis, the computa- tion of linguistic distance.between each pair of sites, can be computed as Leven- shtein distance between phonetic strings. This correlates closely with the much more laborious technique of determining and counting isoglosses, and is more ac- curate than the more familiar metric of computing Hamming distance based on whether vocabulary entries match. In the actual clustering step, traditional ag- glomerative clustering works better thaxl the top-down technique of partitioning around medoids. When agglomerative clustering of phonetic string comparison distances is applied to Gaelic, reasonab...
