It remains unclear what laryngeal and vocal tract adjustments are elicited in speakers by this emphasis on oral vibratory sensations. Using a three-dimensional phonation model, this study aims to identify laryngeal and epilaryngeal adjustments that might produce maximal oral vibratory sensations during phonation, as quantified by the oral sound pressure level (SPL), and thus are likely to be elicited in voice therapy at different semi-occluded vocal tract configurations. Results show that maximum oral SPL occurs at intermediate vocal fold adduction configurations characterized by a trade-off between glottal gap and vocal fold vertical thickness. Epilaryngeal tube narrowing further increases the oral SPL in an open vocal tract, but has little effect on oral SPL in semi-occluded vocal tracts. Laryngeal and epilaryngeal configurations producing the maximum oral SPL generally have lower peak vocal fold contact pressure when producing a target output SPL. These favorable configurations are more easily identified in open vocal tracts than semi-occluded vocal tracts. However, semi-occlusion increases both the mean and dynamic oral pressure, which may familiarize speakers with oral vibratory sensations and facilitate adoption of favorable laryngeal configurations.<\/jats:p>","DOI":"10.1121\/10.0012365","type":"journal-article","created":{"date-parts":[[2022,7,8]],"date-time":"2022-07-08T12:43:30Z","timestamp":1657284210000},"page":"302-312","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Oral vibratory sensations during voice production at different laryngeal and semi-occluded vocal tract configurations"],"prefix":"10.1121","volume":"152","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2379-6086","authenticated-orcid":false,"given":"Zhaoyan","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Head and Neck Surgery, University of California, Los Angeles , 31-24 Rehabilitation Center, 1000 Veteran Ave., Los Angeles, California 90095-1794, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2022,7,8]]},"reference":[{"key":"2023081003080894000_c1","doi-asserted-by":"publisher","first-page":"29","DOI":"10.1044\/1092-4388(2001\/003)","article-title":"A quantitative output-cost ratio in voice production","volume":"44","year":"2001","journal-title":"J.
