Abstract:
1. A training system including instructions stored on one or more computer storage devices and executable by a processing unit to implement components comprising: a training component configured to receive training data including a plurality of training utterances and associated destination classes for the training utterances and the training component configured to invoke a speech recognition component to recognize the training utterances using an acoustic model stored on the one or more computer storage devices and a general language model stored on the one or more computer storage devices for a first training iteration and an iterative language model stored on the one or more computer storage devices for one or more subsequent training iterations and the recognition component outputting recognized text corresponding to the training utterances; a language model training tool configured to process the output recognized text from the speech recognition component and adapt the general language model to provide the iterative language model for the one or more subsequent training iterations; and a classification model training tool configured to receive the output recognized text from the speech recognition component and generate a classification model based upon the recognized text from the training component and the associated destination classes for the training utterances corresponding to the recognized text.
