A system comprises an apparatus having a first voice I/O device; and a voice interface apparatus having a second voice I/O device, and connected to the apparatus by audio connection via short-range wireless communication, wherein the apparatus includes a voice I/O unit that performs voice input and output by using the first voice I/O device or the second voice I/O device; an interaction unit that performs voice interaction with a user; and a process unit that performs a process other than the voice interaction, by using the voice I/O, and the voice I/O unit switches a device used for the voice input and output to the first voice input/output device in a case where the process unit is brought into a first state in which the voice input and output is required when the voice interaction with the user is performed by using the second voice I/O device.

Voice interaction system and information processing apparatus

An information processing device includes a processor configured to acquire voice data of a voice uttered by a user, recognize the acquired voice, determine a timing of an interjection in accordance with time from completion of the voice data acquisition to start of output of a response generated based on a result of the voice recognition, output the interjection at the determined timing of the interjection, and output the response at the time of start of the output of the response.

A voice interactive robot interacting with a user by voice includes a main body, a movable part capable of moving relative to the main body, a following control unit that moves the movable part so that the movable part follows the user, a temporary origin setting unit that sets a temporary origin of the movable part in response to movement of the movable part by the following control unit, an acquisition unit that acquires an operation instruction issued in relation to the movable part, and an operation execution unit that moves the movable part in accordance with the operation instruction using the temporary origin as a reference.

Voice interactive robot and voice interaction system

A voice interaction system includes: a speaker; a microphone having a microphone gain that is set at a low level while a sound is output from the speaker; a voice recognition unit that implements voice recognition processing on input sound data input from the microphone; a sound output unit that generates output sound data and outputs the generated output sound data through the speaker; and a non-audible sound output unit that, when a plurality of sounds are output with a time interval no greater than a threshold therebetween, outputs a non-audible sound through the speaker at least in the interim between output of the plurality of sounds.

A voice I/O apparatus comprises a voice input unit that acquires uttered voice; a connection control unit that controls connection between the voice I/O apparatus and a control apparatus that generates a response to the voice; and an interaction control unit that transmits the acquired voice to the control apparatus, receives the response to the voice, and outputs the response, wherein the connection control unit establishes, between the voice I/O apparatus and the control apparatus, connection of a voice channel over which the voice is transmitted and connection of a data channel over which data other than the voice is transmitted, and terminates the data channel in a case where the connection of the voice channel is not completed within a given time period from the establishment of the connection of the data channel.

An electric current measurement method is provided with: a first controlling process of sweeping a sensing current in a negative magnetization direction in a condition that a core is saturated magnetically in a positive magnetization direction; a second controlling process of sweeping the sensing current in the positive magnetization direction in a condition that the core is saturated magnetically in the negative magnetization direction; a first specifying process of specifying a value of the sensing current if the core is demagnetized in the first controlling process; a second specifying process of specifying a value of the sensing current if the core is demagnetized in the second controlling process; and a calculating process of calculating a value of a target electric current on the basis of the specified current values, the first and second controlling processes being performed repeatedly.
