voweler
goal: insert vowels in text that has no vowels (unless word starts with vowel)
idea:
- precompute double metaphones for dictionary words
- precompute voweless versions of dictionary words
- at runtime, compute double metaphone for input word
- if double metaphone is null (e.g.
metaphone('w')
), get metaphone for word + 'a' - filter dictionary by words whose voweless, sorted representation match input word (sorted)
- compute a score defined as the mean levenshtein distance between primary and secondary metaphones for each dictionary word against input word
- that is, for each dictionary word's metaphones
[dp, ds]
, and the input word's metaphones[ip, is]
, compute(leven(dp, ip) + leven(ds, is)) / 2
- that is, for each dictionary word's metaphones
- filter the wordlist by smallest possible score and grab the top
using a wordlist that is sorted by usage and is relatively small (20k words) shows best results.
status: isn't horrible
use
$ npx voweler hppy brthdy
happy birthday
or import to your project (why?)
const voweler = require('voweler')
const vowelized = voweler('a sntnc wtht vwls')
// a contains without wolves
