7. The method as in claim 6 further comprising: detecting a particular error in translation of the audio signal into the set of text; identifying a type associated with the particular error; and selecting a weighted coefficient for the type associated with the particular error to generate a weighted value for the particular error, the weighted value for the particular error indicating a degree to which the particular error impacts comprehension of the set of text.
6. The method as in claim 1 further comprising: identifying multiple different types of possible translation errors that can occur during translation; and for each of the multiple types of possible translation errors, generating and storing a weighted coefficient value indicative of a degree to which improper translation impacts comprehension of the set of text.
