This investigation assessed the utility of combining both voice contexts for the purpose of auditory-perceptual ratings as well as acoustic measurement of overall voice quality. Sustained vowel and continuous speech samples from 251 subjects with (n = 229) or without (n = 22) various voice disorders were concatenated and perceptually rated on overall voice quality by five experienced voice clinicians. After removing the nonvoiced segments within the continuous speech samples, the concatenated samples were analyzed using 13 acoustic measures based on fundamental frequency perturbation, amplitude perturbation, spectral and cepstral analyses. Stepwise multiple regression analysis yielded a six-variable acoustic model for the multiparametric measurement of overall voice quality of the concatenated samples (with a cepstral measure as the main contributor to the prediction of overall voice quality). The correlation of this model with mean ratings of overall voice quality resulted in r(s) = 0.78. A cross-validation approach involving the iterated internal cross-correlations with 30 subgroups of 100, 50, and 10 samples confirmed a comparable degree of association. Furthermore, the ability of the model to distinguish voice-disordered from vocally normal participants was assessed using estimates of diagnostic precision including receiver operating characteristic (ROC) curve analysis, sensitivity, and specificity, as well as likelihood ratios (LRs), which adjust for base-rate differences between the groups. Depending on the cutoff criteria employed, the analyses revealed an impressive area under ROC = 0.895 as well as respectable sensitivity, specificity, and LR. The results support the diagnostic utility of combining voice samples from both continuous speech and sustained vowels in acoustic and perceptual analysis of disordered voice. The findings are discussed in relation to the extant literature and the need for further refinement of the acoustic algorithm.</abstract> <genre authority="ugent" type="biblio">journalArticle</genre> <genre authority="ugent" type="article">original</genre> <classification authority="biblio-review-status">public</classification> <classification authority="wos">Article</classification> <classification authority="ugent-classification">A1</classification> <classification authority="ugent-publication-status">published</classification> <classification authority="pso">published</classification> <classification authority="ugent-publication-credit">ugent</classification> <classification authority="jcr-category-vigintile">10</classification> <name type="personal" authority="ugent"> <namePart type="given">Youri</namePart> <namePart type="family">Maryn</namePart> <displayForm>Youri Maryn</displayForm> <role> <roleTerm authority="marcrelator" authorityURI="http://id.loc.gov/vocabulary/relators" type="code">aut</roleTerm> <roleTerm type="text" lang="eng">author</roleTerm> </role> <nameIdentifier type="ugent">001998821103</nameIdentifier> <nameIdentifier type="ugent">802002602363</nameIdentifier> <nameIdentifier type="orcid">0000-0003-1491-4068</nameIdentifier> <affiliation>GE37</affiliation> </name> <name type="personal" authority="ugent"> <namePart type="given">Paul</namePart> <namePart type="family">Corthals</namePart> <displayForm>Paul Corthals</displayForm> <role> <roleTerm authority="marcrelator" authorityURI="http://id.loc.gov/vocabulary/relators" type="code">aut</roleTerm> <roleTerm type="text" lang="eng">author</roleTerm> </role> <nameIdentifier type="ugent">801001323297</nameIdentifier> <nameIdentifier type="ugent">976871217490</nameIdentifier> <affiliation>UGent</affiliation> </name> <name type="personal" authority="ugent"> <namePart type="given">Paul</namePart> <namePart type="family">Van Cauwenberge</namePart> <displayForm>Paul Van Cauwenberge</displayForm> <role> <roleTerm authority="marcrelator" authorityURI="http://id.loc.gov/vocabulary/relators" type="code">aut</roleTerm> <roleTerm type="text" lang="eng">author</roleTerm> </role> <nameIdentifier type="ugent">801000413319</nameIdentifier> <nameIdentifier type="ugent">979776493590</nameIdentifier> <affiliation>UGent</affiliation> </name> <name type="personal"> <namePart type="given">Nelson</namePart> <namePart type="family">Roy</namePart> <displayForm>Nelson Roy</displayForm> <role> <roleTerm authority="marcrelator" authorityURI="http://id.loc.gov/vocabulary/relators" type="code">aut</roleTerm> <roleTerm type="text" lang="eng">author</roleTerm> </role> </name> <name type="personal" authority="ugent"> <namePart type="given">Marc</namePart> <namePart type="family">De Bodt</namePart> <displayForm>Marc De Bodt</displayForm> <role> <roleTerm authority="marcrelator" authorityURI="http://id.loc.gov/vocabulary/relators" type="code">aut</roleTerm> <roleTerm type="text" lang="eng">author</roleTerm> </role> <nameIdentifier type="ugent">801001147889</nameIdentifier> <nameIdentifier type="ugent">973840467042</nameIdentifier> <affiliation>UGent</affiliation> </name> <name type="corporate"> <displayForm>Department of Oto-rhino-laryngology and logopaedic-audiologic sciences (ceased 1-10-2018)</displayForm> <nameIdentifier type="ugent">GE19</nameIdentifier> <role> <roleTerm authority="marcrelator" authorityURI="http://id.loc.gov/vocabulary/relators" type="code">sht</roleTerm> <roleTerm type="text" lang="eng">department</roleTerm> </role> </name> <name type="corporate"> <displayForm>University College Ghent</displayForm> <nameIdentifier type="ugent">HOGENT</nameIdentifier> <role> <roleTerm authority="marcrelator" authorityURI="http://id.loc.gov/vocabulary/relators" type="code">sht</roleTerm> <roleTerm type="text" lang="eng">department</roleTerm> </role> </name> <relatedItem type="host"> <titleInfo> <title>JOURNAL OF VOICE</title> </titleInfo> <titleInfo type="abbreviated"> <title>J.
