The first controller changes a material being displayed on the display from the first content to the second content distributed by the fourth controller. ## Claims ### Claim 1 A content display system comprising: a first control device which displays content on a display; a second control device which receives a voice; a third control device which generates a command corresponding to the voice received by the second control device, and determines whether the generated command is a change command to change first content being displayed on the display; and a fourth control device which distributes, to the first control device, second content corresponding to the change command when the third control device determines that the command is the change command, wherein the first control device changes a material being displayed on the display from the first content to the second content distributed by the fourth control device, when the voice received by the second control device includes authentication information to authenticate a user, the third control device adds the authentication information to the change command generated corresponding to the voice, and when the authentication information is not added to the change command, the first control device suspends display of the first content, displays the second content for a certain period of time, and displays the first content again in accordance with the first timetable when the certain period of time ends. ### Claim 2 (depends on 1) The content display system according to claim 1, further comprising storage in which the command generated by the third control device is registered, wherein the first control device transmits, to the third control device, inquiry information inquiring whether the command is registered in the storage, and the third control device determines whether the command registered in the storage is the change command, on the basis of a result of inquiry from the first control device. ### Claim 3 (depends on 2) The content display system according to claim 2, wherein the first control device requests the fourth control device to distribute the second content when the command registered in the storage is the change command, and the fourth control device distributes the second content to the first control device when the request is received from the first control device. ### Claim 4 (depends on 1) The content display system according to claim 1, wherein the fourth control device creates a timetable to manage a content reproduction schedule on the basis of the content, and transmits the created timetable to the first control device, and when acquiring the second content from the fourth control device, the first control device changes a first timetable for reproduction of the first content to a second timetable for reproduction of the second content, and displays the second content on the display in accordance with the second timetable. ### Claim 5 (depends on 1) The content display system according to claim 1, further comprising: a display device including the first control device; a speaker device including the second control device; a cloud server including the third control device; and a management server including the fourth control device, wherein the display device, the speaker device, the cloud server, and the management server are connected to each another via a network.
