Roughness also is considered one of the primary elements of voice quality associated with natural variations across normal voices and is a salient feature of many dysphonic voices. It is known that the roughness of tonal stimuli is dependent on the frequency and depth of amplitude modulation and on the carrier frequency. Here, it is determined if similar dependencies exist for voiced speech stimuli. Knowledge of such dependencies can lead to a better understanding of the acoustic characteristics of vocal roughness along the continuum of normal to dysphonic and may facilitate computational estimates of vocal roughness. Synthetic vowel stimuli were modeled after talkers selected from the Satloff\/Heman-Ackah disordered voice database. To parametrically control amplitude modulation frequency and depth, synthesized stimuli had minimal amplitude fluctuations, and amplitude modulation was superimposed with the desired frequency and depth. Perceptual roughness judgments depended on amplitude modulation frequency and depth in a manner that closely matched data from tonal carriers. The dependence of perceived roughness on amplitude modulation frequency and depth closely matched the roughness of sinusoidal carriers as reported by Fastl and Zwicker [(2007) Psychoacoustics: Facts and Models, 3rd ed. (Springer, New York)].<\/jats:p>","DOI":"10.1121\/1.4937753","type":"journal-article","created":{"date-parts":[[2015,12,24]],"date-time":"2015-12-24T01:30:26Z","timestamp":1450920626000},"page":"3820-3825","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":21,"title":["The psychophysics of roughness applied to dysphonic voice"],"prefix":"10.1121","volume":"138","author":[{"given":"David A.","family":"Eddins","sequence":"first","affiliation":[{"name":"University of South Florida Department of Communication Sciences and Disorders, , 4202 East Fowler Avenue, PCD 1017, Tampa, Florida 33620, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa M.","family":"Kopf","sequence":"additional","affiliation":[{"name":"Michigan State University Department of Communicative Sciences and Disorders, , 1026 Red Cedar Road, Room 109, Oyer Speech and Hearing Building, East Lansing Michigan 48824, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rahul","family":"Shrivastav","sequence":"additional","affiliation":[{"name":"University of Georgia Office of the Vice President for Instruction, , 0309 New College, Athens, Georgia 30602, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2015,12,23]]},"reference":[{"key":"2023071802065102700_c1","volume-title":"Methods for Manual Pure-Tone Threshold Audiometry","author":"ANSI","year":"2010"},{"key":"2023071802065102700_c2","doi-asserted-by":"publisher","first-page":"2892","DOI":"10.1121\/1.420344","article-title":"Modeling auditory processing of amplitude modulation.
