Simple, easy-to-use DAF device for treating childhood stuttering.
Speech-language pathologists, schools, and other institutions: please call for price. Not sold to individual consumers.
Altered Auditory Feedback Features
Delayed auditory feedback (DAF) immediately reduces stuttering about 70% at normal speaking rates without training, mental effort, or abnormal-sounding or abnormally slow speech. 55% carryover fluency after removing the device, without speech therapy. With speech therapy, DAF can induce a slower speaking rate with stretched vowels to make even severe stutterers nearly 100% fluent.
Anti-Background Noise Features
Noise-canceling directional microphone eliminates background noise at the source.
High-frequency filters remove background noise above the user's vocal range.
Dynamic expansion makes loud sounds (e.g., the user's voice) louder and quiet sounds (e.g., other people's voices) quieter.
Other Features
Second headphone jack for speech-language pathologist to plug in headphones to listen in. (Therapist's headphones not included, any standard headphones will work.)
Binaural (two ear) or monaural (one ear) sound. Binaural sound is 25% more effective than monaural sound and is recommended for severe stutterers; mild stutterers can get by with monaural sound.

9-volt battery last about 20 hours. AC adapter (included) doesn't charge the battery.
Removable belt clip.
