“…Changes in body processes (via sensors connected to the computer) are immediately displayed on the screen -the readings change, graphics change or music may be quieter or louder. In order to regulate, adjust the operation of certain systems or organs, a person must consciously use the biological feedback to change the information on the screen in the right direction (Etherington, 2019;Brigas, 2019) This means that a person can learn to adjust the body function with a little effort of will in such a way as to improve his/her health. This technology can be used in the cases of stuttering, alalia, aphasia, dysgraphia and dyslexia, dyslalia, dysarthria, rhinolalia, phonation disorder due to paresis and paralysis of the larynx, functional dysphonia, impaired speech rate, so-called speech anxiety, speech disorders in children and adults with impaired hearing and vision.…”
