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 to proportional control. This accurate monitoring device then enhanced treatment of people who are unable to control excessive or low loudness due 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 wearable biofeedback device is necessary to be used by the patients outside the clinic for self-controlling excessive and low loudness without the need to the continuous therapeutic follow-up in speech pathology clinic. The use of the intelligent biofeedback device proved to be an effective due to its enhanced features. The technical design considerations, enhanced features of the device and evaluation will be presented.
