METHODS AND DEVICES FOR TREATING NON-STUTTERING SPEECH-LANGUAGE DISORDERS USING DELAYED AUDITORY FEEDBACK

摘要

Methods, devices and systems treat non-stuttering speech and/or language related disorders by administering a delayed auditory feedback signal having a delay of under about 200 ms via a portable device. The DAF treatment may be delivered on a chronic basis. For certain disorders, such as Parkinson's disease, the delay is set to be under about 100 ms, and may be set to be even shorter such as about 50 ms or less. Certain methods treat cluttering (an abnormally fast speech rate) by exposing the individual to a DAF signal having a sufficient delay that automatically causes the individual to slow his or her speech rate.
