FluencyCoach

FluencyCoach is a free software application that uses Altered Auditory Feedback technology to simulate the effects of “Choral Speech” (speaking simultaneously with another person).

It has been known for years that choral speech can promote fluency in a person who stutters, and in some people who suffer from Parkinson's Disease.

In recent years, the application of Altered Auditory Feedback has received a lot of attention as the technology underlying such well-known anti-stuttering devices as SpeechEasy, mySpeech and SpeechCoach.
