SoundX/X - Version 1.00.007 The SoundX/X ActiveX control provides Soundex, Extended Soundex, and Metaphone algorithms which convert words or names to codes that represent how the words "sound". This is useful in a database application where users need to find names they may not know how to spell.Soundex is a letter plus digits, Extended Soundex is purely numeric and can result in faster database scans, and Metaphone is letters, which can result in a better match rate, but also takes up more computer storage space. The length of the codes (Soundex, Extended Soundex and Metaphone) is selectable through a property.To generate the code, simply set the Word property with the word or name for which you want a coded entry. When you do this, SoundX generates the codes for all three of the algorithms. All you have to do is read the appropriate property: Soundex, ExtSoundex, or Metaphone.
