Abstract: A system and method for automatically providing quality assurance for user enrollment in a recognition system. Advantageously, the quality a new enrollment (i.e., a newly trained user-dependent prototype) is assessed before the new enrollment is accepted in place of a current enrollment. This quality check is performed by decoding stored user test data using the new enrollment, comparing the decoding results of the new enrollment to the known script used to generate the test data to obtain an accuracy score for the new enrollment, and then comparing the accuracy score for the new enrollment with an accuracy score of a previous qualified enrollment (or, in the case where there is no previous, qualified enrollment, to the accuracy of the speaker independent model). If the decoding results of the new enrollment are acceptable, the new enrollment will be used for recognition; otherwise it will be rejected and discarded.

Abstract: A method for enrolling a user in a speech recognition system, without requiring reading, comprises the steps of: generating an audio user interface having an audible output and an audio input; audibly playing a text phrase; audibly prompting the user to speak the played phrase; repeating the steps of audibly prompting the user not to speak, audibly playing the phrase and audibly prompting the user to speak, for a plurality of further phrases; and, processing enrollment of the user based on the audibly prompted and subsequently spoken phrases. A graphical user interface can also be generated for: displaying text corresponding to the phrases and to the audible prompts; displaying a plurality of icons for user activation; and, selectively distinguishing different ones of the icons at different times by at least one of: color; shape; and, animation.
