Claim 8:
9. A method for determining a path of a user, comprising:
requesting the user to utter in the distance closest to each of the external AI apparatuses,
setting an utterance volume in the closest distance based on a received utterance voice of the user, for each of the plurality of external AI apparatuses,
receiving sound signals of the user from a plurality of external AI apparatuses while the user passes from the first AI apparatus to the second AI apparatus,
calculating a distance and a variation of the distance from each of the plurality of external AI apparatuses to the user based on a volume of the received sound signals and the set utterance volume in a distance closest of the plurality of external apparatuses including the first AI apparatus and the second AI apparatus,
determining candidate areas in which each of the plurality of external AI apparatuses can be disposed based on the distance and the variation of the distance calculated at different times,
determining at least one of locations or relative location relations of the plurality of external AI apparatuses based on the determined candidate areas,
determining a current path of the user using at least one of the locations or the relative location relations based on the calculated distance and the calculated variation of the distance, and
determining a future path of the user to be expected to move from the current path based on the current path and at least one of a record of the path of the user, current time information, weather information, a record of interaction with the user, state information of the plurality of external AI apparatuses, or a content of an utterance voice of the user.
