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.

Great helper

Anyone considering the other expensive in-ear device should get this app first to try out daf and faf assistance. Give it a test run and see if it helps before spending $4,000+ . I personally love this app, it has helped me in so many different situations.

DAF/FAF assistant review

I bought this app to improve my speech. It helps to prepare for presentations, interviews and etc. in my case, I set 280ms delay so that i can fully analize what ive said. and it helps me concentrate, eliminate other unnecessary thoughts. Im sure it can help in other cases too. weakpoints: not compatible with wireless headsets

Nice soft to overcome stuttering problems

A very useful and well-working soft to overcome stuttering problems! I would also like to mention that there is a metodics where such programs can be used not only as a patch but also as a treatment. FAF could force a person to modify the frequency structure of the voice and develop an artist-like voice which would be closing the speech cycle even without FAF programs.

It works well

It works..

Overpriced

App does DAF and FAF ok. There is audio disturbance with the Apple ear bud. 49.99 is too much to pay for this app.
