Abstract: Embodiments of the present invention improve methods of performing speech recognition. In one embodiment, the present invention includes a method comprising receiving a spoken utterance, processing the spoken utterance in a speech recognizer to generate a recognition result, determining consistencies of one or more parameters of component sounds of the spoken utterance, wherein the parameters are selected from the group consisting of duration, energy, and pitch, and wherein each component sound of the spoken utterance has a corresponding value of said parameter, and validating the recognition result based on the consistency of at least one of said parameters.

Abstract: Embodiments of the present invention include a computer-implemented pronunciation training method comprising receiving a spoken utterance from a user, the spoken utterance including a plurality of sub-units of sound, analyzing the speech quality of the plurality of sub-units of sound of the spoken utterance and generating an audio signal of the spoken utterance from the user while simultaneously displaying the speech quality of each sub-unit of the spoken utterance as each sub-unit of the spoken utterance is generated.
