Using the modified one-mass model, the phonation critical condition, including phonation threshold pressure and phonation threshold flow, is analyzed by using the small-amplitude oscillation theory. It is found that the phonation threshold pressure is not sensitive to the change of the prephonatory glottal width at a wide glottal gap. This result agrees with previous experimental observations and suggests that the low slope of dependence of phonation threshold pressure on prephonatory gap found by Chan and Titze [J. Acoust. Soc. Am.\u2008119, 2351\u20132362 (2006)] could be a consequence of the pressure recovery effect at the glottal exit. In addition, it is predicted that the phonation threshold flow is always significantly increased with the prephonatory gap even at a wide prephonatory glottal gap. Therefore, the phonation threshold flow has an advantage in assessing the phonatory system at a wide prephonatory gap in comparison with the phonation threshold pressure. The phonation threshold flow can be a useful aerodynamic parameter for pathological conditions in which the incomplete glottal gap is often seen.<\/jats:p>","DOI":"10.1121\/1.2832328","type":"journal-article","created":{"date-parts":[[2008,3,11]],"date-time":"2008-03-11T22:53:20Z","timestamp":1205276000000},"page":"1637-1641","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":12,"title":["The phonation critical condition in rectangular glottis with wide prephonatory gaps"],"prefix":"10.1121","volume":"123","author":[{"given":"Chao","family":"Tao","sequence":"first","affiliation":[{"name":"University of Wisconsin Medical School Department of Surgery, Division of Otolaryngology Head and Neck Surgery, , Madison, Wisconsin 53792-7375"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jack J.","family":"Jiang","sequence":"additional","affiliation":[{"name":"University of Wisconsin Medical School Department of Surgery, Division of Otolaryngology Head and Neck Surgery, , Madison, Wisconsin 53792-7375"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","reference":[{"key":"2023071220061671800_c1","doi-asserted-by":"publisher","first-page":"2351","DOI":"10.1121\/1.2173516","article-title":"Dependence of phonation threshold pressure on vocal tract acoustics and vocal fold tissue mechanics","volume":"119","year":"2006","journal-title":"J.
