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 origionally 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. If you find this helps your speech with a diagnosed condition please share this in the review to help others see how helpful this can be.

* Known issues *
When using Bluetooth devices there is an additional delay of 60ms added to the feedback system, it's recommended to use headphones to avoid this additional latency.
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. (Over 12 hours continious usage on an iPhone4). Like all apps of this type, it can NOT work during phone calls or with other media apps playing at the same time.
