- Character error rate (CER) is a common metric of the performance of an
15
- automatic speech recognition system.
16

17
-
18
- CER is similar to Word Error Rate (WER), but operates on character instead of
19
- word. Please refer to docs of WER for further information.

- Character error rate can be computed as:
23

25
- CER = (S + D + I) / N = (S + D + I) / (S + D + C)

- S is the number of substitutions,

42
- CER's output is not always a number between 0 and 1, in particular when there
43
- is a high number of insertions. This value is often associated to the
44
- percentage of characters that were incorrectly predicted. The lower the value,
45
- the better the
46
-
47
- performance of the ASR system with a CER of 0 being a perfect score.
