I have found Apache's impelementation of Soundex and Metaphone in Java but I would prefer to keep the text comparison libraries I am using in Scala only if possible. Google searches have yielded me nothing useful in finding either of these algorithms in Scala.
Worst case scenario I can translate these algorithms into Scala but that is less than ideal.
