Abstract
Development of medical devices are expanding rapidly. This is occurring as results of development of high tech electronics, information technology and wireless communication technology. Integrating these technologies helps to provide good, less cost and more effective healthcare services. In this paper a novel intelligent medical biofeedback device is developed for accurate monitoring of the voice loudness using fuzzy logic compared with proportional control. This accurate biofeedback monitoring device then enhanced treatment of people who are unable to control excessive or low loudness due to intellectual disability or aggressive behavior causing loudness levels rejected by others. These people with this behavior may often be unaware of their problems and hence an intelligent biofeedback device is necessary to be used by the patients outside the clinic for self-controlling excessive or low loudness without the need to follow-up in speech pathology clinic for the continuous therapeutic. The use of the intelligent wearable biofeedback device proved to be an effective due to its enhanced features. The design considerations, enhanced features, simulation and evaluation of the device will be presented. (C) 2020 The Authors. Published by Atlantis Press SARL.
