Claim One:
1. A speech recognition device for accurate transformation of acoustic utterances into text, the speech recognition device comprising: an acoustic sensor configured to receive one or more acoustic utterances; one or more memory devices configured to receive and store a set of one or more acoustic models having trained one or more confidence classifiers and to store one or more acceptance metrics defining at least one recognition acceptance condition; automatic speech recognition circuitry including at least one processor unit for executing confidence classifier circuitry, the confidence classifier circuitry being configured to generate a first speech recognition confidence classifier score corresponding to the one or more received acoustic utterances and recognized text based on a first confidence classifier and to generate a second speech recognition confidence classifier score corresponding to the one or more received acoustic utterances and the recognized text based on a second confidence classifier; normalization circuitry connected to the automatic speech recognition circuitry to receive the first and second speech recognition confidence classifier score from the confidence classifier circuitry and to map the second speech recognition confidence classifier score based on the first speech recognition confidence classifier score to yield a mapped speech recognition confidence classifier score that equally or more accurately satisfies the recognition acceptance condition than the first speech recognition confidence classifier score; and a text output interface connected to receive the recognized text from the automatic speech recognition circuitry and to output a signal representing the recognized text as accepted text, if the second speech recognition confidence classifier score satisfies the recognition acceptance condition.
