pub fn score(text: &str, truth: &str, terms: &[String]) -> (f64, f64)Expand description
Term accuracy and word error rate of text against truth.
Term accuracy is the share of terms that survived as whole words -
playwright misspelled as playright is a miss, in the middle of an
otherwise perfect sentence. WER is Levenshtein edits over words over
the truth’s word count; a truth with no words reads as no error rather
than dividing by zero. Neither figure is meaningful for a take, whose
truth is a model’s own output; only the read-aloud passage carries
words somebody knows were said.
