USING LANGUAGE MODELS TO CORRECT MORPHOLOGICAL ERRORS IN TEXT

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for recognizing speech in an utterance. The methods, systems, and apparatus may include actions of obtaining a candidate transcription including a sequence of words and generating morphological variants of one or more of the words from the candidate transcription. Additional actions may include, for each morphological variant, generating one or more additional candidate transcriptions that each include the morphological variant. Further actions may include generating respective language model scores for the candidate transcription and the one or more additional candidate transcriptions. Additional actions may include selecting a particular transcription from among the candidate transcription and the one or more additional candidate transcriptions, based on the language model scores.
