DYNAMICALLY BIASING LANGUAGE MODELS

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for speech recognition. In one aspect, a method comprises receiving audio data encoding one or more utterances; performing a first speech recognition on the audio data; identifying a context based on the first speech recognition; performing a second speech recognition on the audio data that is biased towards the context; and providing an output of the second speech recognition.

主权项

1. A method performed by one or more computers, the method comprising:
receiving audio data encoding one or more utterances; generating a recognition lattice of the one or more utterances by performing speech recognition on the audio data using a first pass speech recognizer; determining a specific context for the one or more utterances based on the recognition lattice; in response to determining that the recognition lattice defines the specific context, generating a transcription of the one or more utterances by performing speech recognition on the audio data using a second pass speech recognizer biased towards the specific context defined by the recognition lattice; and providing an output of the transcription of the one or more utterances.
