  • performing speech recognition on an utterance to produce a recognition result for the utterance;

    receiving from a user a selection of a word from the recognized utterance, the selection indicating a bound of a portion of the recognized utterance to be corrected;

    comparing a first alternative transcript to the recognized utterance to be corrected;

    producing a first recognition correction based on the comparison;

    comparing a second alternative transcript to the recognized utterance to be corrected;

    producing a second recognition correction based on the second comparison; and

    replacing a portion of the recognition result with one of the first recognition correction and the second recognition correction;

    wherein a duration of the first recognition correction differs from a duration of the second recognition correction, and the portion of the recognition result replaced includes at one bound a word indicated by the selection and extends for the duration of the one of the first recognition correction and the second recognition correction with which the portion is replaced and includes at least one word other than the user-selected word.
