Anti-stuttering Devices - Computerized Feedback Devices

Computerized Feedback Devices

Computerized feedback devices (such as CAFET or Dr. Fluency) use computer technology to increase control over breathing and phonation. A microphone gathers information about the stutterer’s speech and feedback is delivered on a computer screen. Measurements include intensity (loudness), voice quality, breathing patterns, and voicing strategies. These programs are designed to train features related to prolonged speech, a treatment technique which is frequently used in stuttering therapy. No peer-reviewed studies have been published showing the effectiveness of commercial systems in a clinical context. A study of electromyographic (EMG) feedback in children and adolescents found it to be as effective as other treatments (home-based and clinic-based smooth speech training) in the short and longterm.
