1. A method for voice recognition, comprising: deducing and/or specifying a theoretic identification result for a recognition process of an utterance in a voice recognition system; receiving a spoken theoretic identification result based upon other recognition process of the utterance from a user; further adapting a confidence measure of the theoretic identification result for recognition of the utterance, according to the spoken theoretic identification result; adapting a confidence threshold taking into account the confidence measure; and classifying theoretic identification results into categories based on the confidence threshold, wherein the categories include at least one of a first category in which an utterance to be recognized has been determined to be reliably recognized, a second category in which the utterance to be recognized has been determined to be unreliably recognized, and a third category in which it has been determined that the utterance does not form part of a vocabulary to be recognized.
