In order to evaluate the regularity of vocal fold vibration, frequency and amplitude perturbation of EGG waves during sustained phonation were measured with a laboratory computer. The data were compared to the degree of hoarseness evaluated by auditory perception and by sound spectrographic analysis. Frequency and amplitude perturbation measures showed some overlap between normal and pathological groups. However, there was a close relation between perturbation analysis of EGG waves and degree of hoarseness (Spearman\u2019s rank correlation coefficient rs=0.73, p&amp;lt;0.0005). Amplitude perturbation was found to be a more sensitive measure of the irregularity of vocal fold vibration than frequency perturbation.<\/jats:p>","DOI":"10.1121\/1.394083","type":"journal-article","created":{"date-parts":[[2005,10,7]],"date-time":"2005-10-07T14:35:41Z","timestamp":1128695741000},"page":"58-62","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":38,"title":["Frequency and amplitude perturbation analysis of electroglottograph during sustained phonation"],"prefix":"10.1121","volume":"80","author":[{"given":"Tomoyuki","family":"Haji","sequence":"first","affiliation":[{"name":"Vocal Dynamics Laboratory, Lenox Hill Hospital, 100 East 77th Street, New York, New York 10021"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Horiguchi","sequence":"additional","affiliation":[{"name":"Haskins Laboratories, 270 Crown Street, New Haven, Connecticut 06511"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Baer","sequence":"additional","affiliation":[{"name":"Haskins Laboratories, 270 Crown Street, New Haven, Connecticut 06511"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wilbur J.","family":"Gould","sequence":"additional","affiliation":[{"name":"Vocal Dynamics Laboratory, Lenox Hill Hospital, 100 East 77th Street, New York, New York 10021"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"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\/80\/1\/58\/9430153\/58_1_online.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/80\/1\/58\/9430153\/58_1_online.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,7,17]],"date-time":"2023-07-17T20:05:47Z","timestamp":1689624347000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/80\/1\/58\/623041\/Frequency-and-amplitude-perturbation-analysis-of"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1986,7,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1986,7,1]]}},"URL":"https:\/\/doi.org\/10.1121\/1.394083","relation":{},"ISSN":["0001-4966","1520-8524"],"issn-type":[{"value":"0001-4966","type":"print"},{"value":"1520-8524","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[1986,7]]},"published":{"date-parts":[[1986,7,1]]}}}
