US 10,832,679 B2 · Method and system for correcting speech-to-text auto-transcription using local context of talk

Abstract

One embodiment provides a computer program product for improving accuracy of a transcript of a spoken interaction. The computer program product comprises a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a processor to cause the processor to identify a plurality of patterns in the transcript. The plurality of patterns are indicative of a group of acoustically similar words in the transcript and a corresponding local, sequential context of the group of acoustically similar words. The program instructions are further executable by the processor to cause the processor to predict conditional probabilities for the group of acoustically similar words based on a predictive model and the plurality of patterns, detect one or more transcription errors in the transcript based on the conditional probabilities, and correct the one or more transcription errors by applying a multi-pass correction on the one or more transcription errors.

Dependent claims

A computer program product for improving accuracy of a transcript of a spoken interaction, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

identify a group of acoustically similar words in the transcript;
identify a corresponding local, sequential context of the group of acoustically similar words, wherein the corresponding local, sequential context is indicative of one or more common features across portions of the transcript in which the group of acoustically similar words occur;
predict conditional probabilities for the group of acoustically similar words based on a predictive model and the corresponding local, sequential context;
detect one or more transcription errors in the transcript based on the conditional probabilities;
and
correct the one or more transcription errors by applying a multi-pass correction on the one or more transcription errors.

3 more elements

A system for improving accuracy of a transcript of a spoken interaction, comprising:

at least one processor;
and
a non-transitory processor-readable memory device storing instructions that when executed by the at least one processor causes the at least one processor to perform operations including:
identifying a group of acoustically similar words in the transcript;
identifying a corresponding local, sequential context of the group of acoustically similar words, wherein the corresponding local, sequential context is indicative of one or more common features across portions of the transcript in which the group of acoustically similar words occur;
predicting conditional probabilities for the group of acoustically similar words based on a predictive model and the corresponding local, sequential context;
detecting one or more transcription errors in the transcript based on the conditional probabilities;
and
correcting the one or more transcription errors by applying a multi-pass correction on the one or more transcription errors.
