A Wireless Digital Public Address with Voice Alarm and Text-to-speech Feature for Different Campuses

Adaption of the new technology is a prerequisite for the business's survival and to meet the quality standard. The public address system is widely used in all areas of living; it helps the host speaker to easily disperse the desired messages. This study aimed to develop a wireless digital broadcasting with voice alarm and text-to-speech (TTS) features that can wirelessly transmit audio signals from the main campus to its satellite campus over long distances. Also, the prototype has a TTS feature that can offer high-quality and stable speech. The main campus is the Colegio de San Antonio de Padua (CSAP) located at Guinsay, Danao City Cebu, Philippines with a satellite campus at Brangay Suba, Danao City, with a distance of not less than four kilometers and not greater than five kilometers from the main campus. The researcher used the descriptive developmental method of research as the systematic study of designing, developing, and evaluating programs that must meet the criteria of internal consistency and effectiveness. The rapid prototyping model was used during the system development while the criteria in McCall’s Factor Model were used to test the system according to its usability, applicability, and efficiency
