The present invention relates to an electric wheelchair having a voice recognition drive system comprising: a traveling apparatus main body unit which has a plurality of wheels in a lower end thereof; a seating unit which is installed in an upper end of the traveling apparatus main body unit so as to be able to be lifted; an auxiliary robot leg unit which is able to be inserted into and protrude from the traveling apparatus main body unit, and which includes multi-joint driven by an external force; and a voice recognition drive unit which extracts a preset command from an externally input voice, and which drives the plurality of wheels, lifts the seating unit, and drives the auxiliary robot leg unit.

A holding tool for use in holding a first portion of an item, such as a hydraulic coupling, in a static position, while a torque application tool applies torque and rotates a second portion of the item. The holding tool helps reduce twisting of the first portion relative to the second portion when torque is applied. The holding tool also communicates with a controller when the tool is in use. For example, the tool communicates with the controller in response to a user applying a force to the tool in a direction of the first portion the tool is engaged with. That force releases pressure on a switch that activates a communication signal for communication to the controller. This allows the controller to monitor whether the holding tool was used in conjunction with a torque wrench to tighten the coupling; thereby providing an error reducing function.

Techniques for notification are presented. The techniques may include detecting a natural language phrase concerning an event at a geographic location in speech broadcast by a radio system, determining at least one search criteria from the natural language phrase, searching video surveillance data based on the at least one search criteria, such that search results are obtained, forming computer generated speech corresponding to the search results, and delivering the computer generated speech audibly.

A method and an apparatus for detecting correctness of a pitch period, where the method for detecting correctness of a pitch period includes determining, according to an initial pitch period of an input signal in a time domain, a pitch frequency bin of the input signal, where the initial pitch period is obtained by performing open-loop detection on the input signal, determining, based on an amplitude spectrum of the input signal in a frequency domain, a pitch period correctness decision parameter, associated with the pitch frequency bin, of the input signal, and determining correctness of the initial pitch period according to the pitch period correctness decision parameter. Hence, the method and apparatus for detecting correctness of the pitch period improve, based on a relatively less complex algorithm, accuracy of detecting correctness of the pitch period.

The present invention relates to a beverage supply apparatus comprising a sensing unit, a microphone, an artificial intelligence unit and a control unit. The control unit: activates the microphone when an object is detected; recognizes first sound data of a user when the first sound data is sensed via the activated microphone; acquires information associated with the user on the basis of the first sound data; stores the acquired information associated with the user; and determines a menu corresponding to the object on the basis of the information associated with the user and the first sound data.

Techniques for capturing spoken user inputs while a device is prevented from capturing such spoken user inputs are described. When a first device becomes incapable of capturing spoken user inputs intended for a system, a second device, for capturing such spoken user inputs, may be identified. The second device may be identified based on the second device being connected to a same vehicle computing system as the first device. The second device may be enabled to capture spoken user inputs, intended for the system, until the first device is again able to capture such spoken user inputs.

Audio content associated with a received verbal utterance is received. An operational meaning of the received verbal utterance comprising a compound input is recognized and determined at least in part by: determining that a first subset of the received verbal utterance is associated with a first recognized input; determining that a second subset of the received verbal utterance is associated with a second recognized input; and storing data that associates with a scene identifier a set of commands that includes a first command associated with the first recognized input and a second command associated with the second recognized input.

A method, performed by an electronic apparatus, of executing an application, based on a voice input of a user, and the electronic apparatus are provided. The method includes performing voice recognition on the voice command for executing the application, determining a target page among a plurality of pages displayable when the application is executed, based on a result of the voice recognition, generating a virtual input sequence for displaying a second screen corresponding to the target page, instead of a first screen currently displayed, and executing the application in response to the virtual input sequence.

A voice recognition device provided with a processor configured to determine a breathing period immediately before uttering which is a period in which a lip of a target person has moved with breathing immediately before uttering based on a captured image of the lip of the target person, to detect a voice period which is a period in which the target person is uttering without including the breathing period immediately before uttering determined above based on the captured image of the lip of the target person captured, to acquire a voice of the target person, and to recognize the voice of the target person based on the voice of the target person acquired above within the voice period detected above.
