Abstract
A method for comparing a first audio data source with a plurality of audio data sources, wherein the first audio data source has an utterance spoken by a first person and the plurality of audio data sources have the same utterance spoken by a second person. The method includes performing a speech recognition function on the first audio data source to isolate at least one element of the first audio data source. The method also includes comparing the isolated element with a corresponding element in the plurality of audio data sources and determining whether the utterance spoken by the first person contained an error based on the comparison.
Claims21
A method for comparing a first audio data source with a plurality of audio data sources, wherein the first audio data source has an utterance spoken by a first person and the plurality of audio data sources have the same utterance spoken by a second person, the method comprising:
- performing a speech recognition function on the first audio data source to isolate at least one element of the first audio data source;
- comparing the isolated element with a corresponding element in the plurality of audio data sources;
- and
- determining whether the utterance spoken by the first person contained an error based on the comparison.
An apparatus, comprising:
- an audio capture module for receiving a first spoken utterance, wherein the first spoken utterance is spoken in a language that is not native to a speaker of the first spoken utterance;
- and
- a comparison module for comparing an element of the first spoken utterance with a corresponding element in audio data from a plurality of audio data sources and for determining whether the first spoken contained an error based on the comparison, wherein the audio data from a plurality of audio data sources are spoken in the language, wherein the language is native to each speaker of the audio data from a plurality of audio data sources, and wherein the first spoken utterance and the audio data from a plurality of audio data sources are substantially similar in content.
A system, comprising:
- an audio input device;
- and
- a comparison device in communication with the audio input device, wherein the comparison device includes:
- an audio capture module for receiving a first spoken utterance, wherein the first spoken utterance is spoken in a language that is not native to a speaker of the first spoken utterance;
- and
- a comparison module for comparing an element of the first spoken utterance with a corresponding element in audio data from a plurality of audio data sources and for determining whether the first spoken contained an error based on the comparison, wherein the audio data from a plurality of audio data sources are spoken in the language, wherein the language is native to each speaker of the audio data from a plurality of audio data sources, and wherein the first spoken utterance and the audio data from a plurality of audio data sources are substantially similar in content.
An apparatus, comprising:
- means for performing a speech recognition function on a first audio data source to isolate at least one element of the first audio data source, wherein the first audio data source has an utterance spoken by a first person;
- means for comparing the isolated element with a corresponding element in a plurality of audio data sources, wherein the plurality of audio data sources have the same utterance as that spoken by the first person that is spoken by a second person;
- and
- means for determining whether the utterance spoken by the first person contained an error based on the comparison.
A computer readable medium having stored thereon instructions which, when executed by a processor, cause the processor to:
- perform a speech recognition function on a first audio data source to isolate at least one element of the first audio file, wherein the first audio data source has an utterance spoken by a first person;
- compare the isolated element with a corresponding element in a plurality of audio data sources, wherein the plurality of audio data sources have the same utterance as that spoken by the first person that is spoken by a second person;
- and
- determine whether the utterance spoken by the first person contained an error based on the comparison.
