1. A method comprising: identifying, based on past interactions with a user, an adaptation schema which, when applied to a speech recognition model, increases a likelihood the speech recognition model will recognize misrecognized speech from the user relative to an unadapted speech recognition model; determining, via a processor, that the user has previously repeated speech inputs based on interactions with the user prior to initiating the dialog, to yield a determination; and when the determination indicates that the user has previously repeated speech inputs, adapting a speech recognition model using the adaptation schema before an expected repeat speech input, wherein adapting the speech recognition model further comprises modifying two of an acoustic model, a language model, and a semantic model.
