How it works
Metaphone is a phonetic algorithm that improves on Soundex by using more sophisticated rules for English pronunciation. It produces variable-length codes and handles silent letters, consonant combinations, and vowel sounds more accurately. For example, it correctly identifies that "knight" and "night" sound the same, which Soundex misses. Metaphone is commonly used in spell checkers and search engines.
