The consequences are perturbations of the acoustic speech signal which are perceived as a hoarse voice. By means of appropriate image processing techniques, the vocal fold dynamics are extracted from digital high-speed videos. This study addresses the approach to obtain a parametric description of the spatio-temporal characteristics of the vocal fold oscillations for the aim of classification. For this purpose a biomechanical vocal fold model is introduced. An automatic optimization procedure is developed for fitting the model dynamics to the observed vocal fold oscillations. Thus, the resulting parameter values represent a specific vibration pattern and serve as an objective quantification measure. Performance and reliability of the optimization procedure are validated with synthetically generated data sets. The high-speed videos of two normal voice subjects and six patients suffering from different voice disorders are processed. The resulting model parameters represent a rough approximation of physiological parameters along the entire vocal folds.<\/jats:p>","DOI":"10.1121\/1.2902167","type":"journal-article","created":{"date-parts":[[2008,5,12]],"date-time":"2008-05-12T15:14:03Z","timestamp":1210605243000},"page":"2717-2732","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":39,"title":["Spatio-temporal quantification of vocal fold vibrations using high-speed videoendoscopy and a biomechanical model"],"prefix":"10.1121","volume":"123","author":[{"given":"Raphael","family":"Schwarz","sequence":"first","affiliation":[{"name":"University of South Carolina Department of Communication Sciences and Disorders, , Columbia, South Carolina 29208"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"D\u00f6llinger","sequence":"additional","affiliation":[{"name":"University Hospital Erlangen Department of Phoniatrics and Pediatric Audiology, , Medical School, Erlangen, Germany 91054"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Wurzbacher","sequence":"additional","affiliation":[{"name":"University Hospital Erlangen Department of Phoniatrics and Pediatric Audiology, , Medical School, Erlangen, Germany 91054"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulrich","family":"Eysholdt","sequence":"additional","affiliation":[{"name":"University Hospital Erlangen Department of Phoniatrics and Pediatric Audiology, , Medical School, Erlangen, Germany 91054"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00f6rg","family":"Lohscheller","sequence":"additional","affiliation":[{"name":"University Hospital Erlangen Department of Phoniatrics and Pediatric Audiology, , Medical School, Erlangen, Germany 91054"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","reference":[{"key":"2023080201001269400_c1","doi-asserted-by":"publisher","first-page":"429","DOI":"10.1016\/S0892-1997(05)80206-1","article-title":"Measure of vocal function during changes in vocal effort level","volume":"9","year":"1995","journal-title":"J.
