The world's number 1 DAF app is used by thousands of people in over one hundred countries. *

DAF Pro is the best DAF app available for Android, has the lowest delay (latency) of all apps and also offers the choral effect.

We have measured the latency to be 20ms on Google Pixel phones but this will vary from device to device.

DAF Professional has been developed to be the leading app to help people who stutter / stammer or have Parkinson's Disease. It helps people to slow their rate of speech down which makes it sound clearer to others.

DAF Professional has been designed and tested by a certified and practicing Speech and Language Therapist (MSc, PGDip, BAHons, HPC registered and member of RCSLT). DAF Professional is the most effective and efficient Delayed Auditory Feedback (DAF) currently on the Android Market. No other app delivers the low latency required for effective use.

Delayed Auditory Feedback (DAF) is a well established speech and language therapy tool which helps people to speak more slowly. However, until recently, devices have been cumbersome to carry around, difficult to adjust, very expensive and therefore not widely used.

DAF was originally developed for people who stutter / stammer, but has since been shown to work with people with other speech difficulties, such as those with Parkinson's Disease (Downie et al., 1981; Dagenaise, Outhwood & Lee, 1998; Lowit et al., 2006 and most recentely Lowit et al., 2010).

It works by enabling someone to hear his or her speech in an altered manner. This disruption to the normal auditory feedback loop causes the speaker to slow down. Research has shown that DAF will be of benefit to approximately a third of people who have a stammer or Parkinson's. Clinical research has not been carried out as yet on other client groups. However, DAF may well be of benefit to people with other medical speech conditions.

DAF Professional is an easy to use professional speech therapy tool which could make a huge difference to you or someone you know.

User reviews

This app did not work for me, my mom told me about it and it costed 2.99 only for it to not work in the slightest. I couldn't do anything with it, just an honest waste of time, money, and high expectations. Do not purchase this app, also I would like a refund as soon as possible.

Poor. Can see it working, however crashes and hangs on a very modern phone and earpieces. Doesn't run in background, doesn't run when screen locked even with correct permissions. On android 13 on a Nothing phone.
