Metaphone()

edit

Metaphone is a phonetic algorithm, an algorithm published in 1990 for indexing words by their English pronunciation.

The algorithm produces variable length keys as its output, as opposed to Soundex's fixed-length keys.

Similar sounding words share the same keys.

Metaphone( str=string );

Returns: String

Argument Description
str
string, required 		edit

The input string

Examples

edit 
// reduces names to a key or code based on their English pronunciation, such that similar sounding names share the same key.
name1 = metaphone(str = "Smith");
name2 = metaphone(str = "Smythe");
name3 = metaphone(str = "Smithfield");
dump(name1); // SM0
dump(name2); // SM0
dump(name3); // SM0F
