Abstract: Example implementations described herein are directed to a dialog system with self-learning natural language understanding (NLU), involving a client-server configuration. If the NLU results in the client is not confident, the NLU will be done again in the server. In the dialog system, the human user and the system communicate via speech or text information. The examples of such products include robots, interactive voice response system (IVR) for call centers, voice-enabled personal devices, car navigation system, smart phones, and voice input devices in the work environments where the human operator cannot operate the devices by hands.

Abstract: A sound signal processing method and device are provided for separating sounds of the respective sound sources even when sounds are recorded asynchronously by a plurality of devices. Specifically, the present invention comprises the steps of instructing each of the plurality of devices to output a reference signal of a different frequency, receiving each of the reference signals output from the speaker of the plurality of devices according to the instruction, receiving sound signals in which each of the reference signals output from the speaker of the plurality of devices is input into the microphone of the plurality of devices, calculating a time shift amount of each of the devices based on each of the received reference signals output from the speaker and the received sound signals, and separating the plurality of signal signals input into the microphone of the plurality of devices based on the calculated time shift amount.

Abstract: Disclosed is a method for synchronizing visual information and auditory information characterized by extracting visual information included in video, recognizing auditory information in a first language that is included in a speech in the first language, associating the visual information with the auditory information in the first language, translating the auditory information in the first language to auditory information in a second language, and editing at least one of the visual information with the auditory information in the second language so as to associate the visual information and the auditory information in the second language with each other.

Abstract: A control apparatus is configured to execute: acquisition processing of acquiring, from at least one data acquisition apparatus, as data on a second object, time series data on a series of pieces of information on the second object that has been collected since the at least one data acquisition apparatus detected the second object; determination processing of determining whether or not the first and the second object are identical to each other based on information on the first and the second object; and storage processing of storing, when the determination processing results that the first and the second object are/aren't identical to each other, the data on the second object and the data on the first object in association with/without each other, and when the determination processing results in a determination that the first object and the second object are not identical to each other.

Abstract: A control system includes: a moving object; and a control apparatus. The moving object is configured to: determine a face direction based on whether or not a face image of the human exists; and control the movement apparatus so that the moving object moves in accordance with path information. The control apparatus is configured to: detect a position of the human and the moving object in the area; calculate, based on the position of the human and the moving object, and the face direction, the path information for allowing the moving object to arrive at any one of a position within a predetermined range from the human and in a field of view of the human and a position within the predetermined range from the human and outside the field of view of the human; and transmit the path information to the moving object.
