Abstract: An embodiment of the present invention relates to an intelligent communication system to enable a visitor to talk with a household or a manager with a beacon bell and a smart device held by the visitor. According to the embodiment of the present invention, the intelligent communication system comprises a calling bell using a beacon signal to transmit an ID of the calling bell to a mobile phone and a smart device of a user who is in a near position. A call request screen corresponding to the calling bell ID is provided to a smartphone or smart device of the user to be displayed to the user. When the user generates a call event on the call request screen, a call signal is transmitted to the server through a call application of the mobile phone or smart device of the user, and a call between a host device and a user terminal is performed in response to the call signal. In the case of a hearing-impaired person, data to discriminate the user is generated in the user terminal to be transmitted to the server to allow the host device to recognize that a user is an impaired-person. At this time, a voice signal transferred from the host terminal to the user terminal is converted into text in the server such that the text is disposed on the user terminal. Moreover, when the hearing-impaired person transmits text through a communication call application to transfer an opinion, the server or the host terminal receives a message of the user in voice. As well as text-voice conversion and voice-text conversion, the server includes a function of transmitting a signal recognized by the hearing-impaired person to display a signal recognized by the user through a lamp, a signboard, and a monitor screen, such as an LCD, through a terminal installed around the user, such that the host terminal or the server transfers a signal required for communications to the terminal installed around the user and the user terminal.
