double_metaphone

Go implementation of Double Metaphone (Lawrence Philips, C/C++ Users Journal, June 2000). Built for Watchman phonetic boosting.

import "github.com/PhonoGrams/double_metaphone"

p, alt := double_metaphone.Encode("Smith") // SM0, XMT
double_metaphone.Match("Smith", "Schmidt") // true (shared XMT)

Primary and alternate codes, capped at 4 characters (Philips). EncodeUncapped keeps the Atkinson unbounded variant.
