BRAIN COMPUTER INTERFACE FOR EMERGENCY TEXT AND SPEECH CARE SYSTEM

Computer Engineering

Brain computer interface (BCI) is one among the thriving emergent technology which acts as an interface between a brain and an external device. BCI for speech is acquiring recognition in various fields. Speech is one among the foremost natural ways to precise thoughts and feelings by articulate vocal sounds. Text is one of the way to keep caregivers an information about emergency needs of patients[21]. The purpose of this study is to restore communication ability through speech, text and display of the people suffering from severe muscular disorders like amyotrophic lateral sclerosis (ALS)[14], stroke which causes paralysis, locked-in syndrome, tetraplegia, Myasthenia gravis. They cannot interact with their environment albeit their intellectual capabilities are intact .Although few recent studies attempt to provide speech based BCI and text based BCI separately. Our work attempts to combine techniques for acquiring signals from brain through brainsense device(EEG signals) to provide speech and text to patients suffering from neurodegenerative diseases through python, Arduino code and some hardware components[1]. Experimental results manifest that the proposed system has an ability to impart a voice emergency command from the computer or laptop, send a text message regarding the emergency command to closed ones and also display the command on LCD screen. Ultimately, Brain computer interface for emergency virtual voice can be an efficient method for restoring communication pathway for paralyzed patients.
