What is Altered Auditory Feedback (AAF)?
Altered Auditory Feedback (AAF) simply means hearing your own voice in a manner that is slightly different from the way you normally hear it. It allows the SpeechEasy user to listen to his or her own voice with a combination of Delayed Auditory Feedback (DAF) and Frequency Altered Feedback (FAF). Using DAF allows the user to hear his or her own voice with a slight delay, similar to an echo. FAF allows the user to hear his or her own voice with a shift in the pitch, so the signal heard is either at a slightly higher or slightly lower pitch than the users own voice. BACK TO TOP 1.
