However, the external validity of the data concerned may be questioned because the data were not based on spontaneous speech samples and were gathered from subjects with unknown treatment histories. With this in mind, the present investigation used young clients with no history of treatment based on prolonged speech and obtained pretreatment and posttreatment acoustic measures from spontaneous speech samples. Acoustic measures showed no significant posttreatment increases in durations of acoustic segments. However, for the acoustic measure of vowel duration and a measure of articulation rate, posttreatment speech samples showed significantly reduced variability. The potential theoretical and practical relevance of these findings is discussed.<\/jats:p>","DOI":"10.1044\/jshr.3503.529","type":"journal-article","created":{"date-parts":[[2014,7,29]],"date-time":"2014-07-29T21:21:35Z","timestamp":1406668895000},"page":"529-536","source":"Crossref","is-referenced-by-count":29,"title":["Variability of Acoustic Segment Durations After Prolonged-Speech Treatment for Stuttering"],"prefix":"10.1044","volume":"35","author":[{"given":"Mark","family":"Onslow","sequence":"first","affiliation":[{"name":"School of Communication Disorders The University of Sydney Sydney, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Janis van","family":"Doorn","sequence":"additional","affiliation":[{"name":"School of Communication Disorders The University of Sydney Sydney, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denis","family":"Newman","sequence":"additional","affiliation":[{"name":"Department of Speech and Hearing The University of Queensland Brisbane, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1310","reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"crossref","first-page":"133","DOI":"10.1016\/0094-730X(87)90019-2","article-title":"Voice onsets and segment durations of normal speakers and beginning stutterers.","volume":"12","author":"Adams M.
