DAF Professional
$2.91About DAF Professional
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, devises have been cumbersome to carry around, difficult to adjust, very expensive and therefore not widely used.
DAF was origionally 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.
DAF Professional works during phone calls on many phones as well as operating as a standalone device.

I tried it and love it. Almost instantly it lowers my pitch and allows me to talk relaxed no problem. The only question I have is how do you use it to make phone calls?

If you struggle with fluency, try this. I do a lot of public speaking and it's made a huge difference to my confidence. I've been a lifelong stammerer and was very sceptical about it. I was wrong. It's changed everything. Just try it.

I installed this on my new phone, but it crashes. I'm running Ice Cream Sandwich. This problem doesn't seem to be unique to this app though. Artefact's DAF crashes too.

I put this on my Galaxy to try with clients as an SLT. It had a minor echo at first, and DAF Professional were quick to sort it out. V reasonable £.

Excellent, works on my Desire S.

Practically useless application. The "zero" delay is too long for normal speaking. It's impossible to make a short delay. Cannot use for normal conversation, public speech and...... The support not responding.
