A Study on the Sound Effect for Improving Customer's Speech Recognition in the TTS-based Shop Music Broadcasting Service

TTS를 이용한 매장음원방송에서 고객의 인지도 향상을 위한 음향효과 연구

This thesis describes the method for well voice announcement using the TTS(Text-To-Speech) technology in the shop music broadcasting service. Offering a high quality TTS sound service for each shop requires a great expense. According to a report on the architectural acoustics the room acoustic indexes such as reverberation time and early decay time are closely connected with a subjective awareness about acoustics. By using the result the customers will be able to recognize better the voice announcement by applying sound effect to speech files made by TTS. The result of an aural comprehension examination has shown better about almost all of the parameters by applying reverb effect to TTS sound.
