SmallTalk Altered Auditory Feedback device for the treatment of Stuttering


Product Description

Altered Auditory Feedback Device for the treatment of stuttering and Hypokinetic Dysarthria.

The Smalltalk anti-stuttering device immediately reduces stuttering, while training you to no longer need the device. It's the world's smallest DAF/FAF anti-stuttering device, and now includes Bluetooth wireless technology.

These miniature electronic devices from Casa Futura, USA, supply delayed auditory feedback (DAF) and frequency-altered auditory feedback (FAF) devices reduce stuttering 70-80% without mental effort, or abnormal-sounding or abnormally slow speech and train carryover fluency so users need the devices less and less. The user hears his or her voice in his or her ear delayed slightly and shifted lower in pitch. The devices are believed to correct the abnormal auditory processing underactivity associated with stuttering in brain imaging studies.

The world’s smallest DAF/FAF device now includes wireless Bluetooth.

Eliminates background noise even in the noisiest environments.

Includes full-size headset to maximize fluency and carryover, miniature wired iPod-style earset, and stylish Bluetooth wireless earset. 

Plugs into telephones. Recharges like a mobile phone.

3" x 2.25" x 0.75"; 2.8 ounces.

Altered Auditory Feedback Features

The SmallTalk 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 about 70% at normal speaking rates. Only Casa Futura Technologies stuttering treatment devices have octave-scale FAF downshifting (pitch shifting) to induce vocal fold relaxation. The SmallTalk has six FAF settings: -1.2 octaves, -0.8 octaves, -0.4 octaves, +0.4 octaves, +0.6 octaves, and +0.8 octaves. The Parkinson's SmallTalk model has five FAF settings: +0.4 octaves, +0.6 octaves, +0.8 octaves, +1.0 octaves, and +1.2 octaves.

Combining DAF and FAF increases effectiveness to 75-80%.

Background Noise Rejection

The SmallTalk is the only anti-stuttering device that works in noisy environments, such as classrooms or restaurants. The Sennheiser PC131 headset has a noise-canceling microphone to eliminate noise at the source. Electronic circuits in the SmallTalk filter high-frequency noise above your vocal range. Moderate (-0.4 octave) FAF effectively reduces stuttering yet is acoustically transparent if the device picks up background noise. The SmallTalk has a push-to-talk button that completely eliminates background noise anywhere. The push-to-talk feature is ideal for a student in a classroom who is mostly listening to the teacher and only is called on to talk occasionally, or if you go out to dinner with friends and spend more time listening than talking. An optional throat microphone eliminates background noise even in extreme conditions.

Telephone Interface

The SmallTalk plugs into telephones.

You hear your voice and the caller's voice in both ears; the caller hears your normal voice. Leave your SmallTalk plugged into your telephone and practice speech therapy on every call.

Three headsets and earsets are included: 


A Sennheiser PC131 full-size headset gives you the best sound quality and maximizes the SmallTalk's effectiveness. By using the full-size headset on telephone calls, in speech therapy, and in stressful conversations such as public speaking, you'll maximize carryover fluency and not need to use the device for lower-stress conversations. The full-size headset will also bring you support from listeners. When you show the full-size headset to listeners and say that you're using an anti-stuttering device, listeners will want to try the device to hear what it sounds like. Then they'll want to talk to you about stuttering and you'll discover that there's no reason to be ashamed or embarrassed about your speech.



A Plantronics Voyager Pro Bluetooth wireless cellphone earset is included with a Jabra A210 Bluetooth adapter. Any Bluetooth wireless cellphone earset can be used with the SmallTalk; the Plantronics Voyager Pro has the best sound and best comfort we've found for wireless earset.




A Plantronics MX100S binaural (two ear) wired iPod-style earset is included. These sound good, are comfortable, and are simple and easy to use. Any other standard wired earset can be used.
