double-metaphone

What is this?

This package exposes a phonetic algorithm. That means it gets a certain string (typically an English word), and turns it into codes, which can then be compared to other codes (of other words), to check if they are (likely) pronounced the same.

When should I use this?

You’re probably dealing with natural language, and know you need this, if you’re here!

Depending on your goals, you likely want to additionally use a stemmer (such as stemmer).
