A Python 3 phonetics library.

Project description

Pyphonetics is a Python 3 library for phonetic algorithms. Right now, the following algorithms are implemented and supported:

  • Soundex
  • Metaphone
  • Refined Soundex
  • Fuzzy Soundex
  • Lein
  • Matching Rating Approach

More will be added in the future.


The module is available in PyPI, just use pip install pyphonetics.


>>> from pyphonetics import Soundex
>>> soundex = Soundex()
>>> soundex.phonetics('Rupert')
>>> soundex.phonetics('Robert')
>>> soundex.sounds_like('Robert', 'Rupert')

The same API applies to every algorithm, e.g:

>>> from pyphonetics import Metaphone
>>> metaphone = Metaphone()
>>> metaphone.phonetics('discrimination')

You can also use the distance(word1, word2, metric=’levenshtein’) method to find the distance between 2 phonetic representations.

>>> from pyphonetics import RefinedSoundex
>>> rs = RefinedSoundex()
>>> rs.distance('Rupert', 'Robert')
>>> rs.distance('assign', 'assist', metric='hamming')


The module was largely based on the implementation of phonetic algorithms found in the Talisman.js ( Node NLP library.
