DAF Long-Term Carryover Fluency
<ul> <li>Nine severe adult stutterers used Casa Futura Technologies DAF devices for an average of thirty minutes per day (ten minutes reading aloud, ten minutes conversation with family member, ten minute telephone call). After three months their stuttering had diminished more than 50% (when speaking without the devices).</li>

<li>A single-subject study with an eleven-year-old boy found that fourteen hours of structured therapy with mediated learning and a Casa Futura Technologies DAF device reduced stuttering from 9% dysfluencies to 5% dysfluencies (when speaking without the device). One year later his stuttering was still 5% dysfluencies. Another fourteen hours of similar treatment reduced his stuttering to 4% dysfluencies.</li> </ul>

Compared to Other Anti-Stuttering Devices
<ul> <li>A Casa Futura Technologies DAF&#047;FAF device was more than twice as effective when compared to another company's DAF&#047;FAF anti-stuttering device.</li> </ul>

Immediate Effects on Stuttering

Stuttering was reduced on average about 80%.</li> <li>Nine adult stutterers called businesses in New York City using a binaural (two ears) DAF&#047;FAF anti-stuttering telephone device. Stuttering was reduced on average about 60%.</li> <li>Binaural (two ears) DAF reduced stuttering 71% and FAF reduced stuttering 64% in eleven adult female stutterers; DAF reduced stuttering 33% and FAF reduced stuttering 31% in eleven adult male stutterers. Stuttering (left scale) while reading five text passages (bottom scale), in women. About 17% of words were stuttered without the device (NAF). Stuttered words with DAF or FAF varied between 2% and 8%.</li> <li>Binaural (two ears) DAF reduced stuttering in all eight stutterers; FAF reduced stuttering in four of eight stutterers.</li> </ul>
