Vision echo

Abstract

One of the most frequently used methods in the speech disfluence therapy is the one based on the acoustical echo. A patient, who is a subject to therapy, hears his own voice with some delay and, thanks to that, his speech fluency increases. As it turned out a therapeutic effect can also be achieved by feedback of the speech with other human senses, such as touch or sight. The article presents a computer program that enables achieving the effect of the visional signal delay from camcorder on a monitor screen.
