What is this?

This package exposes a phonetic algorithm.
That means it gets a certain string (typically an English word), and turns it
into a code, 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 needs, double-metaphone might be better.

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

Install

This package is ESM only.
In Node.js (version 14.14+, 16.0+), install with npm:

shCopy
npm install metaphone

In Deno with esm.sh:

jsCopy
import {metaphone} from 'https://esm.sh/metaphone@2'

In browsers with esm.sh:

htmlCopy
<script type="module">
  import {metaphone} from 'https://esm.sh/metaphone@2?bundle'
</script>

Use

jsCopy
import {metaphone} from 'metaphone'

metaphone('michael') // => 'MXL'
metaphone('crevalle') // => 'KRFL'
metaphone('Filipowitz') // => 'FLPWTS'
metaphone('Xavier') // => 'SFR'
metaphone('delicious') // => 'TLSS'
metaphone('acceptingness') // => 'AKSPTNKNS'
metaphone('allegrettos') // => 'ALKRTS'

With stemmer:

jsCopy
import {metaphone} from 'metaphone'
import {stemmer} from 'stemmer'

metaphone(stemmer('acceptingness')) // => 'AKSPTNK'
metaphone(stemmer('allegrettos')) // => 'ALKRT'
