Soundex phonetic algorithm.

Soundex is one of the earlier phonetics algorithms, specifically designed for surnames, inspiring others such as metaphone.

Depending on your goals, additionally use a stemmer (such as stemmer).

Install:

npm install soundex-code

Use:

var soundex = require('soundex-code')

soundex('phonetics') // => 'P532'
soundex('Ashcraft') // => 'A261'
soundex('Lissajous') // => 'L222'
soundex('Smith') === soundex('Schmit') // => true

soundex('Ashcraftersson', 6) // => 'A26136'
soundex('A', 6) // => 'A000'

Install:

npm install -g soundex-code

Use:
