Specific task composite acoustic models
First Claim
1. A method for recognizing speech comprising the steps of:
- providing a generic model having a generic phonetic baseform representation of a vocabulary of words;
identifying a subset of words relating to an application;
constructing a task specific model for the subset of words;
constructing a composite model by combining the generic model and the task specific model; and
modifying the generic phonetic baseform representation of the subset of words such that the task specific model is used to recognize the subset of words.

Abstract
A method for recognizing speech includes the steps of providing a generic model having a baseform representation of a vocabulary of words, identifying a subset of words relating to an application, constructing a task specific model for the subset of words, constructing a composite model by combining the generic and task specific models and modifying the baseform representation of the subset of words such that the subset of words are recognized by the task specific model. A system for recognizing speech includes a composite model having a generic model having a generic baseform representation of a vocabulary of words and a task specific model for recognizing a subset of words relating to an application wherein the subset of words are recognized using a modified baseform representation. A recognizer compares words input thereto with the generic model for words other than the subset of words and with the task specific model for the subset of words.
