Computer vocal tract models and susceptance plots were used to study the three most important sources of acoustic variability involved in the production of nasalized vowels: velar coupling area, asymmetry of nasal passages, and the sinus cavities. Analysis of the susceptance plots of the pharyngeal and oral cavities, \u2212(Bp+Bo), and the nasal cavity, Bn, helped in understanding the movement of poles and zeros with varying coupling areas. Simulations using two nasal passages clearly showed the introduction of extra pole-zero pairs due to the asymmetry between the passages. Simulations with the inclusion of maxillary and sphenoidal sinuses showed that each sinus can potentially introduce one pole-zero pair in the spectrum. Further, the right maxillary sinus introduced a pole-zero pair at the lowest frequency. The effective frequencies of these poles and zeros due to the sinuses in the sum of the oral and nasal cavity outputs changes with a change in the configuration of the oral cavity, which may happen due to a change in the coupling area, or in the vowel being articulated.<\/jats:p>","DOI":"10.1121\/1.2722220","type":"journal-article","created":{"date-parts":[[2007,6,4]],"date-time":"2007-06-04T14:10:36Z","timestamp":1180966236000},"page":"3858-3873","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":34,"title":["Simulation and analysis of nasalized vowels based on magnetic resonance imaging data"],"prefix":"10.1121","volume":"121","author":[{"given":"Tarun","family":"Pruthi","sequence":"first","affiliation":[{"name":"University of Maryland Speech Communication Laboratory, Institute of Systems Research and Department of Electrical and Computer Engineering, , College Park, Maryland 20742"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carol Y.","family":"Espy-Wilson","sequence":"additional","affiliation":[{"name":"University of Maryland Speech Communication Laboratory, Institute of Systems Research and Department of Electrical and Computer Engineering, , College Park, Maryland 20742"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brad H.","family":"Story","sequence":"additional","affiliation":[{"name":"University of Arizona Speech Acoustics Laboratory, Department of Speech, Language and Hearing Sciences, , Tucson, Arizona 85721"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","reference":[{"issue":"2","key":"2023071307502795100_c1","doi-asserted-by":"publisher","first-page":"1078","DOI":"10.1121\/1.417972","article-title":"Toward articulatory-acoustic models for liquid approximants based on MRI and EPG data.
