Abstract
A method includes receiving audio data corresponding to a query spoken and processing the audio data to generate multiple candidate hypotheses each represented by a respective sequence of hypothesized terms. For each candidate hypothesis, the method includes determining whether the sequence of hypothesized terms includes a source phrase from a list of phrase correction pairs. Each phrase correction pair includes a corresponding source phrase that was misrecognized and a corresponding target phrase replacing the source phrase. When the respective sequence of hypothesized terms includes the source phrase, the method includes generating a corresponding additional candidate hypothesis that replaces the source phrase. The method also includes ranking the multiple candidate hypotheses and each corresponding additional candidate hypothesis generated and generating a transcription of the query spoken by the user by selecting the highest ranking one of the multiple candidate hypotheses and each additional candidate hypothesis.
