Compared with normal speakers, the female PD group as well as the male and female CA patients showed an increased dimension (D) of the EGG. The dimensional complexity of the acoustic signal largely depended on vowel type. Furthermore, the dimension of the acoustic signal was reduced in male PD patients as compared to the respective controls.<\/jats:p>","DOI":"10.1121\/1.419711","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T14:03:08Z","timestamp":1027692188000},"page":"652-654","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":30,"title":["Fractal dimension of sustained vowel productions in neurological dysphonias: An acoustic and electroglottographic analysis"],"prefix":"10.1121","volume":"102","author":[{"given":"Ingo","family":"Hertrich","sequence":"first","affiliation":[{"name":"Department of Neurology, University of T\u00fcbingen, D-72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Werner","family":"Lutzenberger","sequence":"additional","affiliation":[{"name":"Institut of Medical Psychology and Behavioral Neurobiology, University of T\u00fcbingen, D-72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sybille","family":"Spieker","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of T\u00fcbingen, D-72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hermann","family":"Ackermann","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of T\u00fcbingen, D-72076 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","reference":[{"key":"2023071321512051500_far","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1016\/0167-2789(83)90125-2","article-title":"The dimension of chaotic attractors","volume":"7","year":"1983","journal-title":"Physica D"},{"key":"2023071321512051500_her95a","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1177\/000348949510400304","article-title":"Gender-specific vocal dysfunctions in Parkinson\u2019s disease: Electroglottographic and acoustic analyses","volume":"104","year":"1995","journal-title":"Ann.
