The distribution of the SNR measured in multiple overlapping frames in the speech signal was described by a linear combination of the distribution frequencies for SNR=0 dB, 0 dB&amp;lt;SNR&amp;lt;15 dB, and SNR\u226515 dB. The values of the linear combination, the SNR of the vowels, and clinical assignment of the voices to normal and pathologic populations based on laryngoscopic and stroboscopic investigation parameters were used to compare the different evaluations of the voices. The SNR distribution in speech remained stable over signal lengths of more than 30 s. The correlation coefficient between the SNR measure for running speech and the SNR of sustained vowels amounted to only 0.63. The error rate in the discrimination between normal and dysphonic voices amounted to 22.6% in application to sustained vowels and 5.6% when the SNR distribution was used. Possible reasons for the observed discrepancies are discussed, and the results are compared to those of other studies.<\/jats:p>","DOI":"10.1121\/1.399189","type":"journal-article","created":{"date-parts":[[2005,10,13]],"date-time":"2005-10-13T19:34:09Z","timestamp":1129232049000},"page":"2218-2224","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":49,"title":["Acoustic recognition of voice disorders: A comparative study of running speech <i>v<\/i>\n                  <i>e<\/i>\n                  <i>r<\/i>\n                  <i>s<\/i>\n                  <i>u<\/i>\n                  <i>s<\/i> sustained vowels"],"prefix":"10.1121","volume":"87","author":[{"given":"F.","family":"Klingholtz","sequence":"first","affiliation":[{"name":"Department of Phoniatrics, University of Munich, Pettenkoferstr. 4a, 8000 Munich 2, Federal Republic of Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","container-title":["The Journal of the Acoustical Society of America"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/87\/5\/2218\/11926912\/2218_1_online.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/87\/5\/2218\/11926912\/2218_1_online.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T00:32:25Z","timestamp":1690331545000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/87\/5\/2218\/797228\/Acoustic-recognition-of-voice-disorders-A"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1990,5,1]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[1990,5,1]]}},"URL":"https:\/\/doi.org\/10.1121\/1.399189","relation":{},"ISSN":["0001-4966","1520-8524"],"issn-type":[{"value":"0001-4966","type":"print"},{"value":"1520-8524","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[1990,5]]},"published":{"date-parts":[[1990,5,1]]}}}
