Abstract
Implementations relate to correcting a speech recognition hypothesis based on prior correction(s) made by a user and/or fulfillment data associated with fulfilling a request embodied in the speech recognition hypothesis. A candidate speech recognition hypothesis can be generated in response to the user providing a spoken utterance to an application, such as an automated assistant. When a confidence metric for the candidate speech recognition hypothesis does not satisfy a threshold, one or more terms of the candidate speech recognition hypothesis can be compared to correcting data. The correcting data can indicate whether the user previously corrected any term(s) present in the candidate speech recognition hypothesis and, if so, correct the term(s) accordingly. Fulfillment data generated for the candidate hypothesis and/or for the corrected hypothesis can also be processed to determine whether to utilize the candidate hypothesis or the corrected hypothesis in responding to the user.
