The SpeechEasy fits in the ear and is based on “the choral effect,” a phenomenon in which stutterers don’t stutter when speaking the same material in unison with another speaker, or in a chorus, ABC News said.
The device does not cure stuttering, developers said. It aids speech, just as eyeglasses improve vision.
When using the SpeechEasy, stutterers hear a delayed playback of their own voice, at a slightly different pitch, emulating a choral effect, said developer Joseph Kalinowski, a stutterer himself and a speech pathologist at East Carolina University.
