Altered Auditory Feedback Devices
Altered auditory feedback (AAF) such as singing, choral speaking, masking, delayed or frequency altered feedback have long been known to reduce stuttering. Early altered auditory feedback devices were large and thus confined to the laboratory or therapy room, but advances in electronics have permitted increasingly portable devices such as Derazne Correctophone, the Edinburgh Masker, the Vocaltech Clinical Vocal Feedback Device, the Fluency Master and the SpeechEasy. Current devices may be similar in size and appearance to a hearing aid, including in-the-ear and completely-in-the-canal models.

Famous quotes containing the words altered and/or devices:
“The generation of women before us who rushed to fill the corporate ranks altered our expectations of what working motherhood could be, tempered our ambition, and exploded the supermom myth many of us held dear.”
—Melinda M. Marshall (20th century)
“Soon silence will have passed into legend. Man has turned his back on silence. Day after day he invents machines and devices that increase noise and distract humanity from the essence of life, contemplation, meditation.... Tooting, howling, screeching, booming, crashing, whistling, grinding, and trilling bolster his ego. His anxiety subsides. His inhuman void spreads monstrously like a gray vegetation.”
—Jean Arp (1887–1948)
