Voice operation control device and voice operation method

A voice operation control device comprising:

• a processor for executing computer executable instructions stored on a memory, the processor configured to:
• recognize an utterance made by a user and determine whether the recognized utterance is a voice command;
• accept, when the voice command has been uttered, the accepted voice command;
• acquire captured image data captured by a camera that captures a video image;
• perform an action based on the voice command accepted;
• when the recognition result of the accepted utterance indicates that an utterance coincident with a preset voice command at a level equal to or larger than a first threshold has been detected, determine that the recognized utterance is the voice command;
• when the recognition result of the accepted utterance indicates that an utterance that is equal to or larger than a second threshold, which indicates a lower degree of coincidence than the first threshold, but less than the first threshold has been detected more than once within a predetermined time period, determine that the recognized utterance is the voice command;
• store, based on the voice command accepted, the captured image data acquired;
• determine whether the recognized utterance is the voice command for recording a still image of the captured image data;
• store, when detecting the voice command by detecting the utterance coincident with the preset voice command at the level equal to or larger than the first threshold, the still image at the time point at which the voice command is detected;
• and
• the voice command by detecting the utterance equal to or larger than the second threshold but less than the first threshold more than once within the predetermined time period, the still image obtained at the time point at which an initial utterance is detected among the utterances that are detected more than once.

• determine whether the recognized utterance is the voice command for performing a start process of image capturing;
• start, when detecting the voice command by detecting the utterance coincident with the preset voice command at the level equal to or larger than the first threshold, to record the captured image data based on the time point at which the voice command is detected;
