The device is characterized in that it automatically rings the device.

With such a configuration, as long as the visitor remembers the name of the resident, it is possible to specify the destination, and the called name is the name of the resident whose name is registered in advance. When it matches with, the intercom device in the room that has been registered corresponding to the resident's name automatically rings. In other words, even if the visitor forgets the resident's room number, the visit destination can be specified with certainty. Even when the visitor calls the room number instead of the resident's name, the in-room intercom device registered corresponding to the called room number automatically rings.

An intercom system according to a second aspect of the present invention is the intercom system according to the first aspect, wherein the voice-recognized name or room number does not match the name or room number of the resident registered in advance. At this time, the name or room number of the resident who is similar to the voice-recognized name or room number is displayed as a selection candidate on the display part of the lobby intercom device, and from these selection candidates, the visitor's name or room number is selected. It is characterized in that it is configured to select and operate.

With such a configuration, even if the name of the resident called by the visitor is not clearly recognized by voice, or the names of a plurality of resident are similar,
Since the name of the resident, which is similar to the voice-recognized name, is displayed as the selection candidate, it is possible for the visitor to perform a selection operation from the displayed selection candidates and then specify the destination. That is, flexible response from the viewpoint of visitors,
It becomes possible to take so-called interactive correspondence, which can evoke a good impression of visitors. Note that the same measure is taken when the visitor calls the resident's room number.
