System and method for context sensitive inference in a speech processing system

摘要

A method of operating a speech processing system is provided. The method includes translating a portion of a speech record into a plurality of possible words associated with a plurality of contexts, and determining a plurality of correctness values based on a plurality of probabilities that each of the plurality of possible words is correct for each of the plurality of contexts. The method also includes determining which of the plurality of possible words is a correct translation of the portion of the speech record based on the plurality of correctness values.

1. A method of operating a speech processing system, the method comprising:
receiving a portion of a speech record from an audio source, the speech record having been produced by the audio source and transferred by the audio source to the speech processing system; determining, by the speech processing system, from metadata accompanying the portion of the speech record, a first context and a second context for the portion of the speech record, wherein the first context has a first probability of correct context and the second context has a second probability of correct context; processing, by the speech processing system, the portion of the speech record to create a first text translation for the portion of the speech record in the first context, wherein the first text translation has a first probability of correct translation within the first context; processing, by the speech processing system, the same portion of the speech record to create a second text translation for the portion of the speech record in the second context, wherein the second text translation has a second probability of correct translation within the second context; processing, by the speech processing system, the first probability of correct translation and the first probability of correct context, to produce a first probability; processing, by the speech processing system, the second probability of correct translation within the second context and the second probability of correct context, to produce a second probability; selecting, by the speech processing system, the first translation as the correct translation when the first probability is greater than the second probability; and selecting, by the speech processing system, the second translation as the correct translation when the second probability is greater than the first probability.
