Like the original Soundex system, Daitch-Mokotoff Soundex matches similar-sounding names by converting them to the same code. However, Daitch-Mokotoff Soundex is significantly more useful for non-English names than the original system. Major improvements over the original system include: The code is based on the first six meaningful letters rather than four. A letter or combination of letters maps into ten possible codes rather than seven.
