An information processing device comprising: a speech recognition unit configured to perform speech recognition on respective speeches from a plurality of users; a response generation unit configured to generate responses to speeches from a plurality of users, wherein the response generation unit: generates a response indicating an answer to a speech from a user and a response that prompts another user to wait for output of an answer, on the basis of priorities according to order of the speeches from the plurality of users; and generates a response that prompts the non-target user to stand by, the response indicating a result of speech recognition performed on a speech from the non-target user; a decision unit configured to decide methods of outputting the responses to the respective users on the basis of priorities according to order of the speeches from the plurality of users, wherein the decision unit: decides a user having the highest priority as a target user, and decides each of the other one or more users as a non-target user; and causes the target user to occupy a response output method using voice, and allocates a response output method using display to the non-target user; and an output control unit configured to perform control such that the generated responses are output by using the decided methods of outputting the responses, wherein the output control unit performs control such that: a response indicating an answer to a speech of the another user who is standing by is output after the response to the speech from the user finishes; and an image of a response that prompts the non-target user to stand by is displayed, indicating the result of speech recognition performed on the speech from the non-target user is displayed. a speech recognition unit configured to perform speech recognition on respective speeches from a plurality of users; a response generation unit configured to generate responses to speeches from a plurality of users, wherein the response generation unit: generates a response indicating an answer to a speech from a user and a response that prompts another user to wait for output of an answer, on the basis of priorities according to order of the speeches from the plurality of users; and generates a response that prompts the non-target user to stand by, the response indicating a result of speech recognition performed on a speech from the non-target user; generates a response indicating an answer to a speech from a user and a response that prompts another user to wait for output of an answer, on the basis of priorities according to order of the speeches from the plurality of users; and generates a response that prompts the non-target user to stand by, the response indicating a result of speech recognition performed on a speech from the non-target user; a decision unit configured to decide methods of outputting the responses to the respective users on the basis of priorities according to order of the speeches from the plurality of users, wherein the decision unit: decides a user having the highest priority as a target user, and decides each of the other one or more users as a non-target user; and causes the target user to occupy a response output method using voice, and allocates a response output method using display to the non-target user; and decides a user having the highest priority as a target user, and decides each of the other one or more users as a non-target user; and causes the target user to occupy a response output method using voice, and allocates a response output method using display to the non-target user; and an output control unit configured to perform control such that the generated responses are output by using the decided methods of outputting the responses, wherein the output control unit performs control such that: a response indicating an answer to a speech of the another user who is standing by is output after the response to the speech from the user finishes; and an image of a response that prompts the non-target user to stand by is displayed, indicating the result of speech recognition performed on the speech from the non-target user is displayed. a response indicating an answer to a speech of the another user who is standing by is output after the response to the speech from the user finishes; and an image of a response that prompts the non-target user to stand by is displayed, indicating the result of speech recognition performed on the speech from the non-target user is displayed.
