Research suggests that externally generated digital vibrotactile speech feedback serves as an effective fluency enhancer. The present purpose was to test the fluency-enhancing effects of self-generated digital vibrotactile speech feedback on stuttering frequency. Adults who stutter read passages aloud over the telephone, both with and without digital vibrotactile speech feedback. Digital vibrotactile speech feedback was operationally defined as feeling the vibrations of the thyroid cartilage with the thumb and index finger while speaking. Analysis indicated that self-generated digital vibrotactile speech feedback reduced overt stuttering frequency by an average of 72%. As the specific neural mechanisms associated with stuttering and fluency enhancement from tactile speech feedback remain unknown, theoretical implications and clinical applications were discussed.<\/jats:p>","DOI":"10.2466\/pms.108.1.271-280","type":"journal-article","created":{"date-parts":[[2009,4,28]],"date-time":"2009-04-28T05:15:32Z","timestamp":1240895732000},"page":"271-280","source":"Crossref","is-referenced-by-count":6,"title":["Effects of Digital Vibrotactile Speech Feedback on Overt Stuttering Frequency"],"prefix":"10.1177","volume":"108","author":[{"given":"Gregory J.","family":"Snyder","sequence":"first","affiliation":[{"name":"The Laboratory for Stuttering Research, Department of Communication Sciences, & Disorders, University of Mississippi"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dwight","family":"Waddell","sequence":"additional","affiliation":[{"name":"Department of Health, Exercise Science &, Recreation Management, University of Mississippi"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Blanchet","sequence":"additional","affiliation":[{"name":"Department of Speech Pathology and Audiology, State University of New York at Fredonia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lennette J.","family":"Ivy","sequence":"additional","affiliation":[{"name":"Department of Communication Sciences, & Disorders, University of Mississippi"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2009,2,1]]},"reference":[{"key":"bibr1-pms.108.1.271-280","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcomdis.2004.03.001"},{"key":"bibr2-pms.108.1.271-280","volume-title":"On the causal mechanisms of stuttering.","author":"Alm P.","year":"2005"},{"key":"bibr3-pms.108.1.271-280","doi-asserted-by":"publisher","DOI":"10.1044\/jslhr.4003.567"},{"key":"bibr4-pms.108.1.271-280","doi-asserted-by":"publisher","DOI":"10.1044\/jshd.4803.226"},{"key":"bibr5-pms.108.1.271-280","doi-asserted-by":"publisher","DOI":"10.1044\/jshr.2502.208"},{"key":"bibr6-pms.108.1.271-280","doi-asserted-by":"publisher","DOI":"10.1044\/jshr.3701.69"},{"key":"bibr7-pms.108.1.271-280","volume-title":"Research and experiment in stuttering.","author":"Beech H.
