These are devices which do not claim to use DAF or FAF.

Fluency Master (external link) Not advertised as a DAF/FAF device, it is claimed to foster "better hearing of the natural vocal tone associated with speaking". There is some comment on the Stuttering Homepage website in:   Electronic Devices and Stuttering Treatment (external link), and   Auditory Sidetone and the Management of Stuttering: From Wollensak to SpeechEasy (external link) by Richard Merson.

Edinburgh masker (no longer manufactured)
The masker is an electronic aid to alleviating stammering. It generates a 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. However an AAF device (above) may sometimes have the option to produce masking sound. BSA is interested in acquiring working Edinburgh maskers.
