20080228486 | METHOD AND SYSTEM HAVING HYPOTHESIS TYPE VARIABLE THRESHOLDS - A method (and system) for spoken dialog confirmation classifies a plurality of spoken dialog hypotheses, and assigns a threshold to each class of spoken dialog hypotheses. | 09-18-2008 |
20080270135 | METHOD AND SYSTEM FOR USING A STATISTICAL LANGUAGE MODEL AND AN ACTION CLASSIFIER IN PARALLEL WITH GRAMMAR FOR BETTER HANDLING OF OUT-OF-GRAMMAR UTTERANCES - A method (and system) of handling out-of-grammar utterances includes building a statistical language model for a dialog state using, generating sentences and semantic interpretations for the sentences using finite state grammar, building a statistical action classifier, receiving user input, carrying out recognition with the finite state grammar, carrying out recognition with the statistical language model, using the statistical action classifier to find semantic interpretations, comparing an output from the finite state grammar and an output from the statistical language model, deciding which output of the output from the finite state grammar and the output from the statistical language model to keep as a final recognition output, selecting the final recognition output, and outputting the final recognition result, wherein the statistical action classifier, the finite state grammar and the statistical language model are used in conjunction to carry out speech recognition and interpretation. | 10-30-2008 |
20080281598 | METHOD AND SYSTEM FOR PROMPT CONSTRUCTION FOR SELECTION FROM A LIST OF ACOUSTICALLY CONFUSABLE ITEMS IN SPOKEN DIALOG SYSTEMS - A method (and system) of determining confusable list items and resolving this confusion in a spoken dialog system includes receiving user input, processing the user input and determining if a list of items needs to be played back to the user, retrieving the list to be played back to the user, identifying acoustic confusions between items on the list, changing the items on the list as necessary to remove the acoustic confusions, and playing unambiguous list items back to the user. | 11-13-2008 |
20090081995 | SYSTEM FOR INTELLIGENT CONSUMER EARCONS - A system for implementing intelligent consumer earcons, includes: one or more communication devices for carrying out conversations between users and for playing of earcons; one or more tracking and monitoring devices; one or more servers configured with software for implementing the earcons; one or more storage devices for storing a database of earcons, and for storing user profile and preference databases; one or more networks configured for signal communication between the communication devices, the tracking and monitoring devices, the servers, and the storage devices; wherein the monitoring devices are configured to monitor the user, user audio content, and the user's environment; wherein the earcons are chosen from the database of earcons based on the user profile and preferences database; and wherein the playing of individual earcons from the database of earcons is based on the monitored user audio content and environment. | 03-26-2009 |
20090083249 | METHOD FOR INTELLIGENT CONSUMER EARCONS - A method for utilizing earcons, includes: forming a database of earcons; forming a user profile and preferences database; monitoring user audio content; monitoring the user environment; playing a series of earcons from the database of earcons on a user's communication device; wherein the series of earcons are chosen from the database of earcons based on the user profile and preferences database; and wherein the playing of individual earcons from the series of earcons is based on the monitored user audio content and environment. | 03-26-2009 |

20080243507 | NATURAL ERROR HANDLING IN SPEECH RECOGNITION - A user interface, and associated techniques, that permit a fast and efficient way of correcting speech recognition errors, or of diminishing their impact. The user may correct mistakes in a natural way, essentially by repeating the information that was incorrectly recognized previously. Such a mechanism closely approximates what human-to-human dialogue would be in similar circumstances. Such a system fully takes advantage of all the information provided by the user, and on its own estimates the quality of the recognition in order to determine the correct sequence of words in the fewest number of steps. | 10-02-2008 |

20080270136 | Methods and Apparatus for Use in Speech Recognition Systems for Identifying Unknown Words and for Adding Previously Unknown Words to Vocabularies and Grammars of Speech Recognition Systems - The present invention concerns methods and apparatus for identifying and assigning meaning to words not recognized by a vocabulary or grammar of a speech recognition system. In an embodiment of the invention, the word may be in an acoustic vocabulary of the speech recognition system, but may be unrecognized by an embedded grammar of a language model of the speech recognition system. In another embodiment of the invention, the word may not be recognized by any vocabulary associated with the speech recognition system. In embodiments of the invention, at least one hypothesis is generated for an utterance not recognized by the speech recognition system. If the at least one hypothesis meets at least one predetermined criterion, a sword or more corresponding to the at least one hypothesis is added to the vocabulary of the speech recognition system. In other embodiments of the invention, before adding the word to the vocabulary of the speech recognition system, the at least one hypothesis may be presented to the user of the speech recognition system to determine if that is what the used intended when the user spoke. | 10-30-2008 |
