DAF Pro is an app designed by a specialist speech & language therapist for people with speech disorders who speak at a fast rate or stutter/stammer.

The app uses Delayed Auditory Feedback (DAF) to help slow your speech so you can communicate more clearly. DAF works by enabling you to hear their speech in an altered manner. This disruption to the normal auditory feedback loop causes you to slow down and thus speak more clearly.
