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.

Ratings and reviews

The app works for a while then it doesn't it stops sending feedback

The app is very good. However, I find that when I use bluetooth earbuds, the app keeps using the phone microphone. As a result, the volume is low, and I've found over the years that for DAF FAF to be effective you need high volume, not to hear the sound of your own voice. Personally, I would be more than willing to pay for a perfect FAF DAF app that manages to mask the sound of your voice and guarantees a more reliable experience, and I strongly encourage speechtools to add more tweaks.

though this App is a great initiative for stammerers to control their stammer but as far as my experience is concerned, it doesn't work well. I've tried multiple earbuds but it fails to work smoothly. Sometimes it gets hanged, sometimes it produces too much background noise. Overall my experience is very bad. Makers of this App should overcome its weaknesses 🙏🙏🙏🙏🙏
