Artificial intelligence device and 3d agency motion controlling method thereof

An artificial intelligence device comprising:

• a memory configured to store a spoken sentence of a three-dimensional agency;
• and
• a processor configured to control an operation of the three-dimensional agency corresponding to the spoken sentence,
• wherein the processor is configured to:
• upon generating the spoken sentence of the three-dimensional agency, extract a keyword of the spoken sentence;
• acquire related content associated with the keyword of the spoken sentence to detect positions of an object and text in the related content;
• upon determining that an object and text corresponding to the keyword of the spoken sentence exist in the related content, map the positions of the object and the text corresponding to the keyword of the spoken sentence to three-dimensional coordinates;
• output the related content to a surrounding space of the three-dimensional agency;
• and
• control the operation of the three-dimensional agency so that the three-dimensional agency performs an utterance operation corresponding to the spoken sentence and an indication operation of indicating three-dimensional coordinates at which the object and the text of the related content are located.
