| Effectiveness |
More than a dozen studies published in scientific journals. 60-80% immediate stuttering reduction, including stressful situations such as telephone calls to local businesses. Two long-term studies found 55% carryover fluency: after three months using devices 30 minutes per day; and one year after therapy with the device ended. |
