JiWER#

JiWER is a simple and fast python package to evaluate an automatic speech recognition system. It supports the following measures:

  1. word error rate (WER)
  2. match error rate (MER)
  3. word information lost (WIL)
  4. word information preserved (WIP)
  5. character error rate (CER)

These measures are computed with the use of the minimum-edit distance between one or more reference and hypothesis sentences. The minimum-edit distance is calculated using RapidFuzz, which uses C++ under the hood, and is therefore faster than a pure python implementation.

Installation#

You should be able to install this package using poetry: 

$ poetry add jiwer

Or, if you prefer old-fashioned pip and you're using Python >= 3.7:

$ pip install jiwer
