20130272536 | PROVIDING AUDIBLE SIGNALS TO A DRIVER - A method for providing audible signals (such as speech) to a driver of a vehicle which appear to originate from a virtual sound source in front of the driver, so that it will feel normal for the driver to respond interactively by speaking without turning the head to the source of the audible signal. The driver's head position is estimated according to data provided by sensors in the driver's seat, and this position data, together with acoustical characteristics of the vehicle interior, is used to derive a transfer function for filtering electrical audible signals to the loudspeakers to simulate a virtual sound source in front of the driver. | 10-17-2013 |
20130321171 | REDUCING DRIVER DISTRACTION IN SPOKEN DIALOGUE - Methods and systems for reducing driver distraction and situation non-awareness related to a dialogue of an automated dialogue system in a vehicle. For a dialogue policy learning session, driver distraction is introduced as an input into a penalty assigner that assesses dialogue quality, and dialogue acts are extended to include dialogues and dialogue act presentation styles which reduce driver workload related to dialogues. The automated dialogue system policy is developed during the learning process by optimizing the penalties, so that automated dialogue workload is reduced in response to increased workload or anticipated workload on the driver. Methods and systems are presented for responding to both actual workload in regular vehicles as well as anticipated workload in autonomous vehicles. | 12-05-2013 |
20130325482 | ESTIMATING CONGNITIVE-LOAD IN HUMAN-MACHINE INTERACTION - Estimating cognitive-load of a user in human-machine interaction by identifying an expression of cognitive-load within a user expression captured by a dialogue system and using a user model to estimate a level of the cognitive-load based on the expression of cognitive-load. | 12-05-2013 |
20130325483 | DIALOGUE MODELS FOR VEHICLE OCCUPANTS - Methods and apparatus for creating and managing multiple dialogue models in a statistical dialogue modeling system capable of learning, and conducting human-machine dialogues based on selected models. Dialogue models are selected according to feature vectors that describe characteristics of the dialogue participants and their current situation. Mobile apparatus in motor vehicles can provide optimized dialogue service to occupants of the motor vehicles according to vehicle location and route, in addition to personal characteristics of the occupants, whether driver or passenger. When networked via a remote dialogue server, a large pool of dialogue participants is available for automatic building of dialogue models suitable for handling a variety of situations and participants. | 12-05-2013 |
20140316782 | METHODS AND SYSTEMS FOR MANAGING DIALOG OF SPEECH SYSTEMS - Methods and systems are provided for managing speech dialog of a speech system. In one embodiment, a method includes: receiving a first utterance from a user of the speech system; determining a first list of possible results from the first utterance, wherein the first list includes at least two elements that each represent a possible result; analyzing the at least two elements of the first list to determine an ambiguity of the elements; and generating a speech prompt to the user based on partial orthography and the ambiguity. | 10-23-2014 |
