The documented phenomena predominately report effects on the speech signal produced in ambient noise. In comparison, relatively little is known about the underlying articulatory patterns of Lombard speech, in particular for lingual articulation. Here the authors present an analysis of articulatory recordings of speech material in babble noise of different intensity levels and in hypoarticulated speech and report quantitative differences in relative expansion of movement of different articulatory subsystems (the jaw, the lips and the tongue) as well as in relative expansion of utterance duration. The trajectory modifications for one articulator can be relatively reliably predicted by those for another one, but subsystems differ in a degree of continuity in trajectory expansion elicited across different noise levels. Regression analysis of articulatory modifications against durational expansion shows further qualitative differences between the subsystems, namely, the jaw and the tongue. The findings are discussed in terms of possible influences of a combination of prosodic, segmental, and physiological factors. In addition, the Lombard effect is put forward as a viable methodology for eliciting global articulatory variation in a controlled manner.<\/jats:p>","DOI":"10.1121\/1.4939495","type":"journal-article","created":{"date-parts":[[2016,1,9]],"date-time":"2016-01-09T04:16:27Z","timestamp":1452312987000},"page":"151-162","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":32,"title":["Hyperarticulation in Lombard speech: Global coordination of the jaw, lips and the tongue"],"prefix":"10.1121","volume":"139","author":[{"given":"Juraj","family":"\u0160imko","sequence":"first","affiliation":[{"name":"University of Helsinki Institute of Behavioural Sciences, , Siltavuorenpenger 3A - PL 9, 00014 Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0160tefan","family":"Be\u0148u\u0161","sequence":"additional","affiliation":[{"name":"Constantine the Philosopher University Faculty of Arts, , \u0160tef\u00e1nikova 67, 949 74 Nitra, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martti","family":"Vainio","sequence":"additional","affiliation":[{"name":"University of Helsinki Institute of Behavioural Sciences, , Siltavuorenpenger 3A - PL 9, 00014 Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2016,1,8]]},"reference":[{"key":"2023071920012007700_c1","doi-asserted-by":"crossref","unstructured":"Bates, D., M\u00e4chler, M., Bolker, B., and Walker, S.
