What program is best for the computer-assisted phonetic comparison of dialects? We would like to compare several phonetically quite close dialects of a more or less well-documented language (with the respective protoforms available in case they're required for comparison). The aim of the comparison is to see how close the dialects are to each other and if maybe one stands out against the others, as well as to possibly get input for solving the questions of how the language and / or its speakers spread across the area where the dialects are currently spoken (within the possibilities, of course).
