14. The method as in claim 13 , wherein utilizing the weighted values to generate the metric includes: dividing the summation by a total number of words in the reference text to produce a weighted word error rate, the weighted word error rate taking into account different types of errors between the set of text and the reference text.
15. The method as in claim 14 further comprising: utilizing a speech recognition algorithm to convert the audio signal into the reference text; and adapting a language model of the speech recognition algorithm based on the identified errors in the set of text.
