20. A system comprising: at least one processor; and at least one non-transitory storage medium having encoded thereon executable instructions that, when executed by the at least one processor, cause the at least one processor to carry out a method of evaluating a plurality of stored audio phrases and at least one finite state grammar, wherein the at least one finite state grammar defines at least a first plurality of text phrases and wherein the plurality of stored audio phrases correspond to a second plurality of text phrases, the method comprising: determining, for each one text phrase of the first plurality of text phrases and based at least in part on phrase characteristics associated with the plurality of stored audio phrases, whether there is an audio phrase of the plurality of stored audio phrases that corresponds to the one text phrase; and identifying a phrase coverage for the at least one finite state grammar based at least in part on whether the audio phrase corresponds to the text phrase, the phrase coverage indicating whether there are one or more text phrases of the first plurality of text phrases defined by the at least one finite state grammar to which none of the plurality of stored audio phrases corresponds.
