SmallTalk DAF/FAF device — $2495
The SmallTalk 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.
Altered Auditory Feedback (AAF) Features
The SmallTalk provides two types of altered auditory feedback (AAF).
- Delayed auditory feedback (DAF) immediately reduces stuttering about 70% at normal speaking rates without training, mental effort, or abnormal-sounding or abnormally slow speech; and trains 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.
- Pitch-shifting frequency-altered auditory feedback (FAF) immediately reduces stuttering about 70% at normal speaking rates and induces speech motor changes in stutterers. Combining DAF and FAF increases effectiveness. Only Casa Futura Technologies anti-stuttering devices have clinically proven pitch-shifting FAF.
Headsets and Earsets
The SmallTalk works with all standard headphones and microphones. Three headsets and earsets are provided:
- The Logitech H110 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 easier conversations. The full-size headset also allows listeners to try your SmallTalk 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 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.
- Your choice of either a Plantronics Voyager Pro Bluetooth wireless cellphone earset with a Jabra A210 Bluetooth adapter; or an Iasus NT3 throat microphone with a download code for MPiStutter. Jabra has discontinued the A210 Bluetooth adapter. We have to replace the batteries and these units look “refurbished” instead of new.
- The SmallTalk can connect to Bluetooth, FM, and inductive hearing aids via adapters. We have had successful customers with hearing loss and stuttering.
Background Noise Rejection
The SmallTalk is the only AAF device that works in noisy environments, such as classrooms or restaurants. The Logitech H110 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 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.
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. Many states provide Casa Futura Technologies AAF devices free to qualified residents who stutter.
Evidence and Clinical Trials
Two clinical studies have investigated the SmallTalk:
- Eight adult stutterers used SmallTalk devices for oral reading and spontaneous speech (16 tests). The device reduced stuttering in 14 tests. The other two tests found mild stuttering or no stuttering both with and without the device. In 7 of the 16 tests, no stuttering was heard when the device was used. DAF and FAF settings were not standard for all subjects; rather, best settings were selected for each subject. 1
- A study of 30 adult stutterers compared the VoiceAmp and SmallTalk devices. The VoiceAmp was set at 50 ms DAF and 250 Hz addition, with a monaural miniature cellphone earset. The SmallTalk was set at 50 ms DAF and 0.4 octaves downshift, with a binaural full-size headset. Test conditions were 5 minutes reading aloud, 5 minutes monolog, and 10 minutes dialog in a quiet speech clinic. The overall results were that both devices reduced stuttering 34%. The frequency of disfluencies was reduced but there was no change in the duration of disfluencies. No change was found in speaking rate or articulatory rate. Both devices were more effective for blocks than for repetitions or prolongations. Both devices were effective for reading aloud, monologues, and dialogues. Both devices were more effective for moderate and severe stutterers and less effective for mild stutterers. 2
- DAF range 30 milliseconds to 200 milliseconds. User-adjustable.
- FAF range: +0.8, +0.6, +0.4, 0, -0.4, -0.8, -1.2 octaves (seven settings). User-adjustable.
- 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 may be able to use monaural sound.
- 35-7500 Hz frequency range clearly reproduces all vocal frequencies of adults and children.
- Rechargeable battery lasts about 16 hours. Charges like a cellphone.
- Gray case, with belt clip.
- Two 3.5mm jacks for any standard microphone and headphones. One 2.5mm jack for any standard cellphone earset.
- 3″ x 2.25″ x 0.75″ (7.5 x 6 x 1.75 cm). About the size of an iPod Mini.
- 2.8 ounces (80 grams).
