Does anyone know where the code (not commercial stuff) can be found for Metaphone 3 matching for java? Even though apache has implemented Metaphone 1.2 (please see this site: Apache Metaphone 1.2 Implementation). But it didn't implement Metaphone 3. Any help is huge for me, thanks.
The author decided not to release nor the algorithm nor its source for the third version of Metaphone. [Metaphone 3 is sold as source code] You can contact the author via his website to see if some special cases are taken into account.
But you won't find anything legal freely available, sorry
