Whether you're looking to improve your speech clarity or manage speech impairments, DAF Pro is the ultimate tool for individuals with stuttering, stammering, Parkinson’s disease, dysarthria, and other speech and language disorders.

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.

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.
