Matchcode Optimization:Phonetex
Phonetex
Specifics
(pronounced "Fo-NEH-tex") An auditory matching algorithm developed by Melissa Data. It works best in matching words that sound alike but are spelled differently. It is an improvement over the Soundex algorithm.
Summary
A variation of the SoundEx Algorithm. PhonetEx takes into account letter combinations that sound alike, particularly at the start of the word (such as 'PN' = 'N', 'PH' = 'F').
Returns
The Phonetex algorithm is a string transformation and comparison-based algorithm and is performed on the keybuilding. For example, JOHNSON would be transformed to "J565000000" and JHNSN would also be transformed to "J565000000" which would then be considered a Phonetex match after evaluation.

Recommended Usage
Large or enterprise level batch runs where. Using this algorithm will not prevent efficient clustering. Since the algorithm is performed during keybuilding, throughput will be fast.
Databases created via real-time data entry where audio likeness errors are introduced.
Databases of US and English language origin.
Not Recommended For
Databases of non-US and non-English language origin.
Fields whose content data is of type Dictionary or Quantifiable.
Do Not Use With
UTF-8 data. This algorithm was ported to MatchUp with the assumption that a character equals one byte, and therefore results may not be accurate if the data contains multi-byte characters.
