Acoust. Soc. Am. 97(3), 1874\u20131884 (1995)], has seen widespread use throughout the speech community. Herein, an error is corrected in the contact loadings on colliding vocal folds with asymmetric tissue properties, as arises clinically in cases of unilateral paralysis. A revised contact model is proposed that remediates the erroneous asymmetric contact forces. The vibration regime map presented in Steinecke and Herzel illustrating the dynamical behavior of the system is revised using the corrected collision model.<\/jats:p>","DOI":"10.1121\/1.4734013","type":"journal-article","created":{"date-parts":[[2012,9,5]],"date-time":"2012-09-05T18:42:01Z","timestamp":1346870521000},"page":"EL271-EL276","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":17,"title":["Corrected contact dynamics for the Steinecke and Herzel asymmetric two-mass model of the vocal folds"],"prefix":"10.1121","volume":"132","author":[{"given":"David E.","family":"Sommer","sequence":"first","affiliation":[{"name":"University of Waterloo Department of Mechanical and Mechatronics Engineering, , Waterloo, Ontario N2L 3G1, demsomme@uwaterloo.ca","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byron D.","family":"Erath","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Aeronautical Engineering, Clarkson University , Potsdam, New York 13699 berath@clarkson.edu"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matias","family":"Za\u00f1artu","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Universidad T\u00e9cnica Federico Santa Mar\u00eda , Valpara\u00edso, matias.zanartu@usm.cl","place":["Chile"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sean D.","family":"Peterson","sequence":"additional","affiliation":[{"name":"University of Waterloo Department of Mechanical and Mechatronics Engineering, , Waterloo, Ontario N2L 3G1, peterson@uwaterloo.ca","place":["Canada"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2012,9,5]]},"reference":[{"key":"2025080716014200100_c1","volume-title":"Principles of Voice Production","year":"1994"},{"key":"2025080716014200100_c2","doi-asserted-by":"crossref","first-page":"1233","DOI":"10.1002\/j.1538-7305.1972.tb02651.x","article-title":"Synthesis of voiced sounds from a two-mass model of the vocal cords","volume":"51","year":"1972","journal-title":"Bell Syst.
