DAF Assistant implements Delayed Auditory Feedback (DAF) and Frequency-shifting Auditory Feedback (FAF) techniques that are known to help people with stuttering to speak more fluently.
DAF Assistant can be used by people who stutter to control their speech fluency, slow down speech rate, increase confidence level, and develop good speaking habits.
It is known fact that people with stuttering problem usually speak better when do it together with another speaker. This, so called "chorus effect", causes significant increase in speech fluency. Delayed auditory feedback and Frequency-shifting Auditory Feedback simulate chorus effect by changing your own voice.
DAF delays your voice to your ears a fraction of a second. The application provides delay range from 20 to 320 milliseconds with 10 millisecond increments. FAF shifts the pitch of your voice. The application provides pitch shift in the range from one-half octave down to one-half octave up. FAF enhances the effectiveness of the application when used simultaneously with DAF.
At this moment DAF Assistant cannot operate during phone call.
To use the DAF Assistant application you will need "Apple Earphones with Remote and Mic" headset which is available in Apple Store. On iPhone you can also use Bluetooth headset.
This application is compatible with iPhone, iPod Touch, and iPad.
Please visit our web site to see more information about DAF/FAF and this application.

ArtefactSoft must be out of business
February 6, 2014
I purchased this DAF Assistant by ArtefactSoft Software Development for $9.99 for my daughter last year on my iPhone 3 and it worked just fine. I have since upgraded to iPhone 5 and the app no longer works. It opens, but it does nothing. I even deleted and re-downloaded to no avail. I have contacted support at ArtefactSoft via email twice and have not received a response from them. Their website shows their last activity in 2009 so I am assuming the company, ArtefactSoft, is out of business. Their website does not list a business address or a business phone. Just a fax number and non-responsive emails.
Extremely helpful but..
This app really helps listen to how you pronounce your syllables and analyze the source where some stammering comes from in my case. However, I only wish you were able to background this app so it can be used while using apps like iBooks and other reading material. Thank you!
Love this app have it on my iPad mini an on 5s I purchased a bone induction headset so I can hear everything around me. Use it daily would be lost without this app please try to make it work during phone calls so I don't have to use the iPad mini. Thanks to whoever wrote this program! Anxiously awaiting an update!
