Similar to <span class="function"><a href="soundex.html" class="function">soundex()</a></span> metaphone creates the same key for
|
|
similar sounding words. It's more accurate than
|
|
<span class="function"><a href="soundex.html" class="function">soundex()</a></span> as it knows the basic rules of English
|
|
pronunciation. The metaphone generated keys are of variable length.

Metaphone was developed by Lawrence Philips

Algorithms for Programmers", Binstock & Rex, Addison Wesley,

1995].
