Multi-Microphone Speech Recognition Systems and Related Techniques

摘要

A speech recognition system for resolving impaired utterances can have a speech recognition engine configured to receive a plurality of representations of an utterance and concurrently to determine a plurality of highest-likelihood transcription candidates corresponding to each respective representation of the utterance. The recognition system can also have a selector configured to determine a most-likely accurate transcription from among the transcription candidates. As but one example, the plurality of representations of the utterance can be acquired by a microphone array, and beamforming techniques can generate independent streams of the utterance across various look directions using output from the microphone array.

主权项

1. A speech recognition system for resolving far-field utterances, comprising:
a recognition engine configured to concurrently receive a plurality of representations of an utterance and to determine a highest-probability representation of the utterance; and an utterance decoder configured to determine a most-likely transcription corresponding to the highest-probability representation of the utterance.
