Basic Fluency Sytem

Easy-to-use DAF/FAF device for face-to-face conversations or telephone calls.

Altered Auditory Feedback Features

The Basic Fluency System provides two types of altered auditory feedback:

• 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.
• Frequency-shifted auditory feedback(FAF) immediately reduces stuttering at normal speaking rates. Only Casa Futura Technologies stuttering treatment devices have octave-scale FAF downshifting (pitch shifting) to induce vocal fold relaxation, training the user to no longer need the device.

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.
• Quarter-octave FAF effectively reduces stuttering yet is acoustically transparent if the device picks up background noise.

Other Features

• The Basic Fluency System plugs into telephones. You hear your voice and the caller's voice in both ears; the caller hears your normal voice. Leave your Basic Fluency System plugged into your telephone and practice speech therapy on every call. (Not compatible with Nokia cellphones.)
• 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.
• 35-7500 Hz frequency range clearly reproduces all vocal frequencies of adults and children.
• 9-volt battery last about 15 hours. AC adapter (included) doesn't charge the battery.
• Removable belt clip.
• Beige case.
• Two 3.5mm jacks for any standard microphone and headphones. One 2.5mm jack for any standard cellphone earset (except Nokia).
• 4.5" x 2.7" x 0.9" (11.5 cm x 7 cm x 2 cm); about the size of an iPod.
• 4.6 ounces (130 grams).
