摘要： A method (400) includes receiving a training example (302) that includes audio data (202) representing a spoken utterance (12) and a ground truth transcription (204). For each word (310) in the utterance, the method also includes inserting a placeholder symbol before the word identifying a respective ground truth alignment (312, 314) for a beginning and an end of the word, and generating a first constrained alignment (330) for a beginning word piece and a second constrained alignment for an ending word piece. The first constrained alignment is aligned with the ground truth alignment for the beginning of the respective word and the second constrained alignment is aligned with the ground truth alignment for the ending of the respective word. The method also includes constraining an attention head of a second pass decoder (230) by applying the first and second constrained alignments.

摘要： Disclosed herein is a computer-implemented method when executed on data processing hardware causes the data processing hardware to perform operations comprising:
receiving a sequence of audio features characterizing an utterance;
based on the sequence of audio features, generating, using a first-pass decoder model, a plurality of first-pass speech recognition hypotheses, each first-pass speech recognition hypothesis corresponding to a candidate transcription of the utterance;
generating, using a long short-term memory (LSTM) encoder, a first-pass encoding of the plurality of first-pass speech recognition hypotheses; and
based on the sequence of audio features and the first-pass encoding, generating, using a second-pass decoder model, a second-pass hypothesis that rescores the plurality of first-pass speech recognition hypotheses.-
