Phonatory samples were recorded from 20 normal subjects and 60 patients representing 3 laryngeal groups (nodules, paralysis, and functional). The phonatory samples were evaluated by 22 listeners using a 7-point equal-appearing interval scale. Shimmer produced a bivariate correlation of 0.54 with dysphonic severity; harmonic\/noise ratio correlated \u22120.32 with dysphonic severity; and jitter produced no significant correlation with severity. The combination of acoustic variables through multiple regression analysis produced a correlation of 0.56, with only shimmer and average F\n            <jats:sub>0<\/jats:sub>\n            contributing to the correlation. For this particular clinical population, therefore, findings indicated that (a) none of the variables was strongly correlated with dysphonia ratings, and (b) a combination of acoustic predictors was no more successful than a single predictor of dysphonic severity, namely, shimmer.\n          <\/jats:p>","DOI":"10.1044\/jshr.3802.273","type":"journal-article","created":{"date-parts":[[2014,8,26]],"date-time":"2014-08-26T19:09:49Z","timestamp":1409080189000},"page":"273-279","source":"Crossref","is-referenced-by-count":67,"title":["Acoustic Prediction of Severity in Commonly Occurring Voice Problems"],"prefix":"10.1044","volume":"38","author":[{"given":"Virginia","family":"Wolfe","sequence":"first","affiliation":[{"name":"Auburn University at Montgomery Montgomery, AL"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Fitch","sequence":"additional","affiliation":[{"name":"Auburn University Auburn, AL"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Cornell","sequence":"additional","affiliation":[{"name":"Auburn University at Montgomery Montgomery, AL"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1310","reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1044\/jshr.2901.50"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.1044\/jshr.1202.330"},{"key":"e_1_3_2_4_1","volume-title":"Essentials of psychological testing","author":"Cronbach L.
