This is yet another solution to the problem of phonetic similarities. In contrast to Soundex or Metaphone, vowels matter, and it is thus more useful for other (germanic?) languages.
In languages, there are often cases where an automated phonetic analyzer cannot detect the correct pronounciation. I.e. can the german v be pronounced as english v (as in Verb) or as english f (as in verstehen), without obvious reason. In those cases, this analyzer returns both solutions.
