What is DAF Pro? DAF Pro is a professional speech therapy aid for fluency that helps individuals with stuttering, stammering, and Parkinson's to slow their speech rate and improve articulation, making speech clearer and more understandable. Delayed Auditory Feedback (DAF) is a well-established therapeutic tool that allows users to hear their speech with a slight delay, helping them control their pace and reduce impairments in speech flow.

Originally developed for those who stutter or stammer, DAF Pro has been shown to benefit people with a variety of speech conditions, including those suffering from Parkinson’s, dysarthria, and other speech-related impairments. DAF works by disrupting the auditory feedback loop, encouraging the speaker to slow down and articulate more clearly, a technique that has been backed by clinical research.
