A precise flow analysis is performed based on a boundary-layer approximation and the viscous\u2013inviscid interaction between the boundary layer and the core flow. This flow analysis can supply information on the separation point of the glottal flow and the thickness of the boundary layer, both of which strongly depend on the glottal configuration and yield an effective prediction of the flow behavior. When the flow analysis is combined with the modified two-mass model of the vocal fold [Pelorson et al. (1994). J. Acoust. Soc. Am. 96, 3416\u20133431], the resulting acoustic wave travels through the vocal tract and a pressure change develops in the vicinity of the glottis. This change can affect the glottal flow and the motion of the vocal folds, causing source-filter coupling. The property of the acoustic feedback is explicitly expressed in the frequency domain by using an acoustic tube model, allowing a clear interpretation of the coupling. Numerical experiments show that the vocal-tract input impedance and frequency responses representing the source-filter coupling have dominant peaks corresponding to the fourth and fifth formants. Results of time-domain simulations also suggest the importance of these high-frequency peaks in voice production.<\/jats:p>","DOI":"10.1121\/1.3533732","type":"journal-article","created":{"date-parts":[[2011,3,18]],"date-time":"2011-03-18T22:57:43Z","timestamp":1300489063000},"page":"1554-1567","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Voice production model integrating boundary-layer analysis of glottal flow and source-filter coupling"],"prefix":"10.1121","volume":"129","author":[{"given":"Tokihiko","family":"Kaburagi","sequence":"first","affiliation":[{"name":"Kyushu University Faculty of Design, Department of Communication Design Science, , 4-9-1 Shiobaru, Minami-ku, Fukuoka 815-8540, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2011,3,9]]},"reference":[{"key":"2023080407072237300_c1","doi-asserted-by":"publisher","first-page":"3345","DOI":"10.1121\/1.416975","article-title":"Normal modes in a continuum model of vocal fold tissues","volume":"100","year":"1996","journal-title":"J.
