In recent years, wearable devices such as Google Glass and Apple Watch are spreading in society. However, their devices cannot be used the following types of situations. In the case of user wants to quieten children being noisy in a public place, the user wants to speak clearly in a presentation despite being nervous. Therefore, wearable devices are important for the user to control his/her actions. This research aims to achieve involuntary and non-perceptual control of the user’s actions, without inflicting mental stress. The first stage of the research is to design and implement a voice feedback system for voice control. This device is composed of an environmental sound measurement microphone, a speaking voice input microphone, a switch for the white noise function, a minicomputer, and a volume amplifier circuit. A first function of the device change the user’s voice feedback from earphones by the user’s voice loudness. Moreover, a second function of the device that output white noise add in order to consciously increase the use’s voice loudness. In this paper, I describe the proposed vocal volume control and the implementation method of the proposed system.
