1. A method of tuning a speech system comprising: accessing information representing a plurality of utterances for at least one speech-enabled application, the plurality of utterances comprising at least a first type of utterance and a second type of utterance; accessing interpretive information representing an assigned interpretation for at least a portion of the plurality of utterances; determining an appropriate interpretation for the portion of the plurality of utterances; comparing the assigned interpretation for the portion of the plurality of utterances to the appropriate interpretation for the portion of the plurality of utterances; determining that the speech-enabled application more accurately responds to the first type of utterance; and electing to apply a targeted tuning to the speech-enabled application to improve recognition of the second type of utterance.
