Definition and usage

The Metaphone () function computes the Metaphone key for the string.

The Metaphone key represents the English pronunciation of the string.

The Metaphone () function is useful for spell checker.

Note: the Metaphone () function creates the same key for a word that sounds similar.

Note: The resulting metaphone key length is variable.

Tip: Metaphone () is more accurate than the SOUNDEX () function because Metaphone () understands the basic rules of English pronunciation.
