The dataset includes three trisyllabic nonce words (b\u00e1baba, bab\u00e1ba, babab\u00e1), each designed to manipulate the location of lexical stress. These were produced under prosodic conditions that varied in boundary position and focus-induced phrasal prominence, enabling analysis of how preboundary lengthening is distributed across words with different lexical stress locations and how it interacts with prosodic prominence. Articulatory data were collected using electromagnetic articulography (EMA, Carstens AG200), providing kinematic measurements such as movement duration, peak velocity, and displacement of articulatory gestures. The accompanying files allow examination of individual speaker variation in these measures as modulated by prosodic structure, including boundary and prominence effects. While theoretical findings have been reported in a previous study, the full dataset, including detailed descriptions of individual speaker patterns, is made available here. By making these less commonly available articulatory data publicly available, we aim to promote broad reuse and support further research in prosody, articulatory phonetics, and speech production.<\/jats:p>","DOI":"10.3390\/data10120197","type":"journal-article","created":{"date-parts":[[2025,12,2]],"date-time":"2025-12-02T12:39:43Z","timestamp":1764679183000},"page":"197","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Articulatory Data on Preboundary Lengthening Across Prominence Conditions in American English"],"prefix":"10.3390","volume":"10","author":[{"given":"Jiyoung","family":"Jang","sequence":"first","affiliation":[{"name":"Hanyang Institute for Phonetics and Cognitive Sciences of Language, Hanyang University, Seoul 04763, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sahyang","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of English Education, Hongik University, Seoul 04066, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8148-745X","authenticated-orcid":false,"given":"Taehong","family":"Cho","sequence":"additional","affiliation":[{"name":"Hanyang Institute for Phonetics and Cognitive Sciences of Language, Hanyang University, Seoul 04763, Republic of Korea"},{"name":"Department of English Language and Literature, Hanyang University, Seoul 04763, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"EL362","DOI":"10.1121\/1.5005132","article-title":"Articulatory characteristics of preboundary lengthening in interaction with prominence on tri-syllabic words in American English","volume":"142","author":"Kim","year":"2017","journal-title":"J.
