Subjects were two semitrained adult males. Fundamental frequency typically varied directly with subglottic pressure, glottal resistance, and electrical activity of the cricothyroid muscle, and inversely with mean flow rate at middle and upper pitches. Over a lower range of pitch mean subglottic pressure was constant, mean flow rate varied directly with the fundamental but glottal resistance varied inversely. Electrical activity and glottal resistance were positively correlated at middle and upper pitches. Peaks of glottal efficiency occurred over a range of frequencies that could be considered as an optimum pitch range.<\/jats:p>","DOI":"10.1044\/jshr.1102.246","type":"journal-article","created":{"date-parts":[[2014,7,29]],"date-time":"2014-07-29T16:52:19Z","timestamp":1406652739000},"page":"246-267","source":"Crossref","is-referenced-by-count":10,"title":["Parameters of Voice Production: I Some Mechanisms for the Regulation of Pitch"],"prefix":"10.1044","volume":"11","author":[{"given":"William H.","family":"Perkins","sequence":"first","affiliation":[{"name":"University of Southern California, Los Angeles, California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoaki","family":"Yanagihara","sequence":"additional","affiliation":[{"name":"Institute of Laryngology and Voice Disorders, Los Angeles, California"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1310","container-title":["Journal of Speech and Hearing Research"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/pubs.asha.org\/doi\/pdf\/10.1044\/jshr.1102.246","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,12,23]],"date-time":"2019-12-23T10:33:29Z","timestamp":1577097209000},"score":1,"resource":{"primary":{"URL":"http:\/\/pubs.asha.org\/doi\/10.1044\/jshr.1102.246"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1968,6]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1968,6]]}},"alternative-id":["10.1044\/jshr.1102.246"],"URL":"https:\/\/doi.org\/10.1044\/jshr.1102.246","relation":{},"ISSN":["0022-4685"],"issn-type":[{"value":"0022-4685","type":"print"}],"subject":[],"published":{"date-parts":[[1968,6]]}}}
