* The worlds 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 Parkinsons 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 Parkinsons 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 Parkinsons. 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.

Nice

I was impressed with how the microphone automatically shuts off when your not talking so you dont hear background noise. Better than most DAF apps

:3

It did improve stuttering, and would be perfect if was accessible during phone call in iPhone

DAF Pro

Finally a daf tool that all stutterers can use via the iOS platform! Its free. The voice the stutterer hears is their own voice, very natural, not robotic as previous devices have been. I tried it for first time today with a high school senior who stutters pretty severely. It worked perfectly! He was 100% fluent, first time, reading aloud. Incredible experience for him and me! I am an SLP

Awesome!!!

This app has been extremely helpful when working with my stuttering clients. Im still trying to figure out how to work it on my iPad but it works great on my iPhone!

Amazing tool

DAF Pro is elegant and amazing! After a little experimenting with the amount of delay, I have some wonderful results. The app also runs in the background, so you can keep it running while you use other apps like email and web. Thanks for this amazing tool!

No use

I have no use for it, but I use it as an amplifier. My mic built into my Sony earbuds with volume control is sensitive, so i use it As an amplifier for my bad hearing. Delay all the way down, volume up on system and app, and there ya go!
