SPEECH RECOGNITION USING PHONEME MATCHING

摘要

A system, method and computer program is provided for generating customized text representations of audio commands. A first speech recognition module may be used for generating a first text representation of an audio command based on a general language grammar. A second speech recognition module may be used for generating a second text representation of the audio command, the second module including a custom language grammar that may include contacts for a particular user. Entity extraction is applied to the second text representation and the entities are checked against a file containing personal language. If the entities are found in the user-specific language, the two text representations may be fused into a combined text representation and named entity recognition may be performed again to extract further entities.

主权项

1. A computer implemented method of converting an audio input into a text representation, the method comprising:
receiving, at an automatic speech recognition system, the audio input; generating a first text representation of the audio input using the automatic speech recognition system; creating a first phonetic representation of at least one personalized word; creating a second phonetic representation of the first text representation; comparing the first phonetic representation and the second phonetic representation to determine a likelihood that the at least one personalized word is present in the first text representation; and returning an indication whether the at least one personalized word is present in the first text representation, wherein the indication indicates a location of the at least one of personalized word within the first text representation.
