What is DAF Pro: Stuttering,Stammering? Description of DAF Pro: Stuttering,Stammering

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

DAF Professional has been created to help people who stammer or have a neurological disease such as Parkinson's Disease. It helps people to slow their rate of speech which makes it clearer to others.

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

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 delivers incredibly low latency feedback even when running in the background.

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 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 own 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.

When using Bluetooth devices there is an additional delay of 60ms added to the feedback system.

If you do use a Bluetooth headset you may find you need to turn the bluetooth device on after opening the app to enable it.

DAF Professional works when put in the background or the screen is turned off. Like all apps of this type, it can NOT work during phone calls or with other media apps playing at the same time.

If you wish to provide any feedback we would be delighted to hear from you. Please email us at [email protected].

DAF Pro: Stuttering,Stammering Pros

Thank youuuuu so muchWow you cured me god bless ❤️🙏🏽💯.ACEGXVersion: 2.10

So far so goodI have been stuttering for all my life, now 38 years old. I have researched several of the expensive items such as speech easy. I was very eager to spend the thousands for that item but then through further research, I found that apps have been developed. Currently I have downloaded 5 different apps. My main concern is that other apps with delayed auditory feedback seemed to be too delayed. Some have 0ms while others have 4 minimum. In these cases, there seemed to be a longer time response to hear myself, so it didnt help much. This app, though it shows the minimum delay is 23 ms, it seems much quicker than the other apps who show a shorter delay time. I just started working with this, so in about 2 weeks, I will try to post again to give appropriate feedback. So far, I like this app the most as the delay time is very quick so I can hear myself as soon as I am speaking..Pinger user76Version: 1.2

DAF Pro: Stuttering,Stammering Cons

Cannot use pitch changeAny change in pitch causes a static sound..ReentWTVersion: 2.11

Can’t use it during phone callsThe reason I bought a paid app was so that I could use it during phone calls. There are many free DAF apps available for the exact same thing it does. It also shuts off as the phone automatically locks when idle- doesn’t have the ability to play in background. I would rather use the free apps had I known this to be honest..Explicit06Version: 2.5
