Realtime acoustic adaptation using stability measures

摘要

Methods, systems, and computer programs encoded on a computer storage medium for real-time acoustic adaptation using stability measures are disclosed. The methods include the actions of receiving a transcription of a first portion of a speech session, wherein the transcription of the first portion of the speech session is generated using a speaker adaptation profile. The actions further include receiving a stability measure for a segment of the transcription and determining that the stability measure for the segment satisfies a threshold. Additionally, the actions include triggering an update of the speaker adaptation profile using the segment, or using a portion of speech data that corresponds to the segment. And the actions include receiving a transcription of a second portion of the speech session, wherein the transcription of the second portion of the speech session is generated using the updated speaker adaptation profile.

主权项

1. A computer-implemented method comprising:
decoding a first portion of a speech session to generate a first speech recognition hypothesis using a speaker adaptation profile; identifying a segment of the first speech recognition hypothesis; determining that a stability measure for the identified segment satisfies a threshold; triggering a real-time update of the speaker adaptation profile using the identified segment, or using a portion of speech data that corresponds to the identified segment; and decoding a second portion of the speech session to generate a second speech recognition hypothesis using the updated speaker adaptation profile.
