Apparatus, robot, method and recording medium having program recorded thereon

An apparatus for processing a voice, the apparatus comprising:

• a microphone which acquires a sound around the apparatus;
• a processor and a memory that stores a set of executable instructions, wherein when the processor executes the instructions, the apparatus operates as:
• an extractor which extracts a voice from the acquired sound and determines whether the voice includes a speech of an adult;
• a voice recognizer which recognizes the speech of the adult when it is determined that the voice includes the speech of the adult and determines whether the speech of the adult includes a phrase included in a dictionary stored in the memory, wherein the voice recognizer further determines whether the speech of the adult includes a phrase corresponding to a name of a child, based on data indicating the name of the child stored in the memory,
• a speech analyzer configured to determine, after the voice recognizer determines that the speech of the adult includes the phrase included in the dictionary, whether the adult is angry and whether the adult is scolding, based on a physical feature value of the speech of the adult, wherein when it is determined that the speech of the adult includes a phrase corresponding to the name of the child, the speech analyzer further determines that the child is a target person at whom the adult is scolding or angry,
• a controller which causes the apparatus to perform a first process to alert the adult of the adult being angry when it is determined that the adult is angry,
• a loudspeaker, wherein the first process includes either of (i) a process of causing the loudspeaker to output a first sound and (ii) a process of causing the apparatus to perform a first operation,
• a display, wherein the first process further includes either of (i) a process of causing the display to perform a first display and (ii) the process of causing the apparatus to perform the first operation, and
• a camera which acquires video data around the apparatus, wherein the first process further includes either of (i) a process of causing the camera to take an image of the adult and (ii) the process of causing the apparatus to perform the first operation,
• wherein when the processor executes the instructions, the apparatus is further configured to operate as:
• a comparator which determines whether a person included in the video data is the child, based on video data corresponding to the child stored in the memory, and
• a video analyzer which determines, based on the video data, whether an orientation of the child has been changed in a second period after the speech of the adult is recognized when it is determined that the adult is scolding the child and the person included in the video data is the child and determines, based on the video data, whether the child is continuously holding an object by hand in the second period when it is determined that the orientation of the child has not been changed, wherein:
• in the second period, when it is determined that the orientation of the child has not been changed or when it is determined that the child is continuously holding the object by hand, the controller causes the apparatus to perform a second process, and
• the second process includes any of (i) a process of causing the loudspeaker to output a second sound, (ii) a process of causing the apparatus to perform a second operation, (iii) a process of causing the apparatus to perform the second operation and (iv) a process of causing the display to perform a second display.
