Phonetic Algorithm - Common Uses

Common Uses

• Spell checkers can often contain phonetic algorithms. The Metaphone algorithm, for example, can take an incorrectly spelt word and create a code. The code is then looked up in directory for words with the same or similar Metaphone. Words that have the same or similar Metaphone become possible alternative spellings.
• Search functionality will often use phonetic algorithms to find results that don't match exactly the term(s) used in the search. Searching for names can be difficult as there are often multiple alternative spellings for names. An example is the name Claire. It has two alternatives, Clare/Clair, which are both pronounced the same. Searching for one spelling wouldn't show results for the two others. Using Soundex all three variations produce the same Soundex code, C460. By searching names based on the Soundex code all three variations will be returned.
