Background
The Edinburgh Masker is a device historically used to control stuttering. It is no longer manufactured. It consisted of an apparatus strapped across the larynx and then attached to a stethoscope-like system; as a result, the stutterer cannot hear his or her own words.[1]
The masker is an electronic aid to alleviating stammering. It generates a noise, random noise or white noise, which prevents the wearer from hearing the sound of his or her own voice. It is no longer made, and so is now only available second-hand. In contrast, an AAF (Altered Auditory Feedback) device may sometimes have the option to produce masking sound.[2]
The Edinburgh Masker (U.S. Pat. No. 3,566,858 and U.S. Pat. No. 3,773,032) electronically remove the sounds added by nasal and oral cavities, providing only a sound similar to laryngeal vibration. This device reduces or eliminates stuttering in about 90% of users[3]
