Stuttering Research Outcome Summaries
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.”
