DAF Assistant Legacy1.0 - App Store

DAF Assistant Legacy 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 Legacy 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.
