People get a lot of information around them through visual, auditory, and various senses. In particular, audiovisual data is a very important information transfer factor and has developed various technologies and methods for a long time . In previous studies, we have found that a better effect is achieved when the focus of the screen matches the focus of the sound. To that end, it is now possible to create a sound by vibrating a modern display panel, such as an OLED (Organic Light-Emitting Diode). In our previous research, we have studied the research of creating a stereo sound by directly vibrating a single plane, the reason why the sound of this method is better than the ordinary audio system, the position of the exciter optimized for sound quality, the shape of the exciter and the enclosure of speakers. In this study, a research was conducted on the understanding of the audience's voice by the sound composition in an over the top (OTT) environment that supplies a lot of content recently. In the OTT environment, we try to provide picture quality and sound similar to that of a theater. However, the traditional audio method rather lowers the ability to transmit information of voice. The sound system using the proposed sound radiation system overcomes this problem and creates a clear voice, thereby solving the viewer's discomfort with the sound.
