Description

Public address broadcasting system using TTS

The present invention relates to a public address system using Text to Speech (TTS). In particular, after receiving a disaster text message, a necessary message is selected and processed for TTS broadcasting, and the weather information is received by accessing the Meteorological Agency site at a reserved time, and the message is transmitted again to TTS broadcasting. It relates to a public address system using TTS that can be processed.

In general, a public address (PA) system refers to sound equipment built in large facilities such as buildings, government offices, schools, harbors, and airports, and outputs various premises broadcasts related to the use of facilities in ordinary times. In case of an emergency disaster such as a fire, the function outputs an emergency warning sound or an evacuation announcement.

This public address system (PA system) uses high-impedance speakers with an impedance of 500Ω to 2kΩ or more in order to reduce loss due to long-distance transmission, and a plurality of speakers in various areas for premises broadcasting and information broadcasting in case of disaster. are installed, and are divided into analog control type, digital control type, and network type according to the control method.

For example, the analog control type PA system uses analog signals as control signals such as line selectors and audio signals, and although the noise generation factor is high depending on the length or condition of the line, it has higher stability than the digital method, so Used for emergency broadcasts. In the digitally controlled PA system, the control signal uses a digital signal transmission system using relatively simple RS232 communication or RS485 serial communication, and the audio signal uses digital processing using an internal DSP. used in schools, etc. The network-type PA system allows control signals and audio signals to be transmitted through the network. As the Internet network is used, there is no limit to the distance that can be broadcasted, and it can be integrated with audio systems or broadcasting systems such as classrooms, and through matching transformers It has the advantage of overcoming the limitations of sound quality.

Such disaster broadcasting is also transmitted through the airwaves, but in preparation for various disaster situations, it is transmitted in the form of text through various transmission means such as DMB, CBS, RDS, and BIS. In particular, disaster text broadcasting is transmitted to mobile phones equipped with CBS reception function, DMB receiver or DMB special alarm to prevent damage to life and property due to disasters and civil air defense situations.

Meanwhile, in a public address system using Text to Speech (TTS), a program for TTS is installed in a terminal for operating and controlling broadcasting, and through this program, a server capable of providing a TTS function is accessed. Thereafter, the user terminal transmits the input text information to the TTS support server, receives voice information corresponding to the text information transmitted from the TTS support server, and broadcasts it through the speaker.

An example of such a technique is disclosed in Documents 1 to 3 and the like.
