This hearing aid-like device called SpeechEasy helps relieve stuttering by the "Choral effect." This effect, present when stuttering is reduced or eliminated when people speak or sing in unison with others, is replicated by piping a person's own speech back into their ear with a slight delay and on a slightly modified frequency. This in turn makes their brain think they're speaking in unison with someone else. It's definitely a great idea, but the SpeechEasy is only available in Europe as of now. [Medsy via Medgadget]
