## 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`][double-metaphone] might be better.

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

## Install

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

```sh
npm install metaphone
```

In Deno with [`esm.sh`][esmsh]:

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

In browsers with [`esm.sh`][esmsh]:

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

## Use

```js
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`][stemmer]:

```js
import {metaphone} from 'metaphone'
import {stemmer} from 'stemmer'

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

## API

This package exports the identifier `metaphone`.
There is no default export.

### `metaphone(value)`

Get the metaphone code from a given value.

###### `value`

## CLI

```txt
Usage: metaphone [options] <words...>

Metaphone implementation

Options:

  -h, --help           output usage information
  -v, --version        output version number

# output phonetics
$ metaphone considerations detestable
# KNSTRXNS TTSTBL

# output phonetics from stdin
$ echo 'hiccups vileness' | metaphone
# HKKPS FLNS

# FL
```

## Types

This package is fully typed with [TypeScript][].
