Formant-based measures of either the stuttered or fluent speech of children and adults who stutter have generally failed to obtain compelling evidence in support of the hypothesis that these individuals differ in the timing or degree of coarticulation. Here, we used a sensitive acoustic technique\u2013spectral coefficient analyses\u2013that allowed us to compare stuttering and nonstuttering speakers with regard to vowel-dependent anticipatory influences as early as the onset burst of a preceding voiceless stop consonant. Eight adults who stutter and eight matched adults who do not stutter produced C\n                    <jats:sub>1<\/jats:sub>\n                    VC\n                    <jats:sub>2<\/jats:sub>\n                    words, and the first four spectral coefficients were calculated for one analysis window centered on the burst of C\n                    <jats:sub>1<\/jats:sub>\n                    and two subsequent windows covering the beginning of the aspiration phase. Findings confirmed that the combined use of four spectral coefficients is an effective method for detecting the anticipatory influence of a vowel on the initial burst of a preceding voiceless stop consonant. However, the observed patterns of anticipatory coarticulation showed no statistically significant differences, or trends toward such differences, between the stuttering and nonstuttering groups. Combining the present results for fluent speech in one given phonetic context with prior findings from both stuttered and fluent speech in a variety of other contexts, we conclude that there is currently no support for the hypothesis that the fluent speech of individuals who stutter is characterized by limited coarticulation.\n                  <\/jats:p>","DOI":"10.1177\/0023830917695853","type":"journal-article","created":{"date-parts":[[2017,3,9]],"date-time":"2017-03-09T04:58:00Z","timestamp":1489035480000},"page":"31-42","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Spectral Coefficient Analyses of Word-Initial Stop Consonant Productions Suggest Similar Anticipatory Coarticulation for Stuttering and Nonstuttering Adults"],"prefix":"10.1177","volume":"61","author":[{"given":"Santosh","family":"Maruthy","sequence":"first","affiliation":[{"name":"All India Institute of Speech and Hearing, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongqiang","family":"Feng","sequence":"additional","affiliation":[{"name":"Institute of Acoustics, Chinese Academy of Sciences, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ludo","family":"Max","sequence":"additional","affiliation":[{"name":"University of Washington, USA; Haskins Laboratories, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,3,9]]},"reference":[{"key":"bibr1-0023830917695853","volume-title":"A handbook on stuttering","author":"Bloodstein O.","year":"2008"},{"issue":"1","key":"bibr2-0023830917695853","first-page":"65","volume":"25","author":"Caruso A.
