FastWER

A PyPI package for fast word/character error rate (WER/CER) calculation

  • fast (cpp implementation)
  • sentence-level and corpus-level WER/CER scores
  • Unicode code point-based character error rates

Installation

pip install fastwer

Example

import fastwer
hypo = ['This is an example .', 'This is another example .']
ref = ['This is the example :)', 'That is the example .']

# Corpus-Level WER: 40.0
fastwer.score(hypo, ref)
# Corpus-Level CER: 25.5814
fastwer.score(hypo, ref, char_level=True)

# Sentence-Level WER: 40.0
fastwer.score_sent(hypo[0], ref[0])
# Sentence-Level CER: 22.7273
fastwer.score_sent(hypo[0], ref[0], char_level=True)

Character-level scoring treats each Unicode code point as one character. Normalize text before scoring if canonically equivalent representations, such as composed and decomposed accented characters, should compare as equal.
