An Intelligent Acoustic Communication System for Aphasia Forbearings

Abstract

Communication is a process of transferring the information from one entity to another. Speech is one of the most common modes of communication. The person who suffers from severe motor impairment, severe cerebral palsy, head trauma and spinal injuries cannot able to express their thoughts in the form of speech. The development of direct neurocontrol over virtual or physical devices would improve quality of life immensely for those who suffer from impaired communication skill. In this methodthe development of an Electroencephalogram (EEG) based Brain Computer Interface (BCI) system is proposed. The thoughts of the individual are extracted from the brain activity of a particular disordered patient and it is stored in the form of data.The word frequencies for basic essential requirements such as food, water and assisting work should be generated and the data is stored in matrix representation. Already obtained EEG signal and the word frequencies should be compared and the matched frequencies are stored separately. Finally, the matched frequencies of corresponding words are displayed using LCD display and then the words are converted into audible signal by using speech synthesizer.
