There was evidence of articulatory compensation to recover tract-variable (constriction) trajectories in speech produced with a lip approximation under sufficiently constrained conditions. However, in more extensive studies of lip and velar approximations, the recovered tract-variable trajectories were also different from those of the data-producing utterance. This phenomenon can occur because the matching criterion in the analysis-by-synthesis procedure is an acoustic criterion and the correspondence between the tract-variable trajectories and the acoustic output is not exact. While there may be some tract-variable compensation to attain a good acoustic match, there is evidence of a correspondence between how well the tract-variable trajectories match and how well the formant frequencies match in particular instances.<\/jats:p>","DOI":"10.1121\/1.415220","type":"journal-article","created":{"date-parts":[[2005,10,18]],"date-time":"2005-10-18T17:07:01Z","timestamp":1129655221000},"page":"595-608","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":6,"title":["Task dynamic and articulatory recovery of lip and velar approximations under model mismatch conditions"],"prefix":"10.1121","volume":"99","author":[{"given":"Richard S.","family":"McGowan","sequence":"first","affiliation":[{"name":"Haskins Laboratories, 270 Crown Street, New Haven, Connecticut 06511-6695"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mindy","family":"Lee","sequence":"additional","affiliation":[{"name":"Haskins Laboratories, 270 Crown Street, New Haven, Connecticut 06511-6695"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","container-title":["The Journal of the Acoustical Society of America"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/99\/1\/595\/11588964\/595_1_online.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/99\/1\/595\/11588964\/595_1_online.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,7,25]],"date-time":"2023-07-25T04:18:31Z","timestamp":1690258711000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/99\/1\/595\/766614\/Task-dynamic-and-articulatory-recovery-of-lip-and"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1996,1,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1996,1,1]]}},"URL":"https:\/\/doi.org\/10.1121\/1.415220","relation":{},"ISSN":["0001-4966","1520-8524"],"issn-type":[{"value":"0001-4966","type":"print"},{"value":"1520-8524","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[1996,1]]},"published":{"date-parts":[[1996,1,1]]}}}
