1. A method of dynamic re-configurable speech recognition comprising the steps of:
- determining parameters of a background model of a received voice request;
determining parameters of a transducer model;
determining an adapted speech recognition model for a speech recognition model based on at least one of the background model and the transducer model; and
determining information in the voice request based on the adapted speech recognition model.

Abstract
Speech recognition models are dynamically re-configurable based on user information, background information such as background noise and transducer information such as transducer response characteristics to provide users with alternate input modes to keyboard text entry. The techniques of dynamic re-configurable speech recognition provide for deployment of speech recognition on small devices such as mobile phones and personal digital assistants as well environments such as office, home or vehicle while maintaining the accuracy of the speech recognition.
