A prospective complementary study concerning 43 female patients and 3 controls is presented. &lt;i&gt;Methods:&lt;\/i&gt; Objective measures included fundamental frequency (Fo), intensity, jitter, signal-to-noise ratio (SNR), Lyapunov coefficient (Lya), oral airflow (OAF), estimated subglottic pressure (ESGP), maximum phonatory time (MPT) and vocal range. A jury of 4 experienced listeners was instructed to classify voice samples (continuous speech) according to the G (overall dysphonia) component of the GRBAS score on a Visual Analogue Scale (VAS) secondarily transformed in a scale ranging from 0 for normal to 3 for severe dysphonia. &lt;i&gt;Results:&lt;\/i&gt; It was shown that a nonlinear combination of only 7 parameters in women (vocal range, Lya, ESGP, MPT, OAF, SNR, and Fo) and 6 parameters in men (vocal range, Lya, OAF, ESGP, Fo, SNR) allowed classification of 81% voice samples in the same grade as the jury in women and 84% in men. In the prospective study, 80.5% were correctly classified with the same set of objective measurements. &lt;i&gt;Discussion:&lt;\/i&gt; The relative importance of the different objective parameters in this type of discriminant analysis is dealt with. Special emphasis is placed on Lya.<\/jats:p>","DOI":"10.1159\/000096547","type":"journal-article","created":{"date-parts":[[2006,12,22]],"date-time":"2006-12-22T23:18:32Z","timestamp":1166829512000},"page":"20-30","source":"Crossref","is-referenced-by-count":33,"title":["Objective Voice Analysis in Dysphonic Patients: New Data Including Nonlinear Measurements"],"prefix":"10.1159","volume":"59","author":[{"given":"Ping","family":"Yu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renaud","family":"Garrel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Nicollas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maurice","family":"Ouaknine","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antoine","family":"Giovanni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2006,12,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1007%2Fs004050000299"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1159%2F000266406"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016%2FS0892-1997%2801%2900053-4"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2FS0892-1997%2897%2980040-9"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016%2FS0892-1997%2899%2980040-X"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1159%2F000066150"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1159%2F000021485"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1159%2F000266220"}],"container-title":["Folia Phoniatrica et Logopaedica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/96547","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/96547","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T02:54:14Z","timestamp":1745463254000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000096547"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,12,18]]},"references-count":8,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2006,12,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000096547","archive":["Portico"],"relation":{},"ISSN":["1021-7762","1421-9972"],"issn-type":[{"value":"1021-7762","type":"print"},{"value":"1421-9972","type":"electronic"}],"subject":[],"published":{"date-parts":[[2006,12,18]]}}}
