Note that since N is the number of words in the reference, the word error rate can be larger than 1.0, and thus, the word accuracy can be smaller than 0.0.

Then, we'll use the formula to calculate the WER: From this, the code is self explanatory: def wer(ref, hyp ,debug=False): r = ref.split() h = hyp.split() #costs will holds the costs, Search Eligible Titles Special offers not for use by distributors or book sellers.

  1. Unlike the Levenshtein distance, however, the operations are on words and not on individual characters.
  2. Your cache administrator is webmaster.
  3. This may be particularly relevant in a system which is designed to cope with non-native speakers of a given language or with strong regional accents.

WER can get arbitrary large, because the ASR can insert an arbitrary amount of words. For text dictation it is generally agreed that performance accuracy at a rate below 95% is not acceptable, but this again may be syntax and/or domain specific, e.g. There is thus some merit to the argument that performance metrics should be developed to suit the particular system being measured. Python Calculate Word Error Rate When reporting the performance of a speech recognition system, sometimes word accuracy (WAcc) is used instead: W A c c = 1 − W E R = N − S −

Calculation Interestingly, the WER is just the Levenshtein distance for words. A further complication is added by whether a given syntax allows for error correction and, if it does, how easy that process is for the user. Library IS&T Copyright 2016. 360 pages.

The pace at which words should be spoken during the measurement process is also a source of variability between subjects, as is the need for subjects to rest or take a
