Another way to decide which stuttering treatment programs are most effective is to look for stuttering research that summarizes many studies and then draws conclusions as to which programs are best.
Stuttering Research Outcome Summaries
One such “meta-analysis” as they are called is Stuttering Treatment Research 1970–2005.
Here is the statement of results from the study:
“The most powerful treatments for adults, with respect to both speech outcomes and social, emotional, or cognitive outcomes, appear to combine variants of prolonged speech…” Once again prolonged speech techniques are key to recovery.
Another cross stuttering treatment study is Meta-analysis of the effects of stuttering treatment. This study compares several approaches to stuttering treatment. These include “attitude” – talking about your feeling about stuttering and “airflow” – starting voicing with a puff of air.
“Prolonged speech and gentle onset techniques evidenced better gains in the short term and long term than either attitude or airflow techniques. These four seem preferable to any of the other reported treatments and were certainly better than no treatment.”
A recently developed program with positive experimental outcomes
The MPI (Modifying Phonation Intervals) program produces powerful continuous voicing that reduces or eliminates stuttering in adults and teenagers. Dr. Roger Ingham, a speech scientist at the University of California, Santa Barbara, developedThe MPI program. He conducted 30 years of careful research to determine what factors really controlled stuttering in an experimental environment. He found that by reducing the production of short interval phonations (voice segment of less than 100 msec.) stuttering was reduced or eliminated consistently. Therefore, reducing short interval phonations just increase the incidence of long interval phonations. Actually, the goal of effective prolonged speech programs is to increase long interval phonations. The difference is that subjects did not need to start treatment at a very slow speaking rate. And then try to shape normal rates into natural sounding speech. The subject starts out at a normal speech rate that sounds natural from the beginning.
Using current stuttering research to determine the effectiveness of treatment programs is the best way to find one that works for you.
