This has not been studied in contemporary commercial music (CCM) singers. This study explores the vocal economy of twang-like voices in CCM singers using the \u201cquasi-output-cost ratio\u201d (QOCR). Ten CCM singers sang the syllable [pa:] loudly, using neutral and twang-like voices at low and high pitches. QOCR, electroglottografic contact quotient, sound pressure level, air pressure, and inverse filtering measures were obtained. QOCR showed no significant differences between the voice types. Air pressure measures were significantly higher in twang-like voices, suggesting increased aerodynamic effort to compensate for supralaryngeal constriction. New tools for studying vocal economy in singing are warranted.<\/jats:p>","DOI":"10.1121\/10.0039036","type":"journal-article","created":{"date-parts":[[2025,9,17]],"date-time":"2025-09-17T12:42:56Z","timestamp":1758112976000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Vocal economy in contemporary commercial music singers: A pilot study on twang-like voices"],"prefix":"10.1121","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8883-3052","authenticated-orcid":false,"given":"Marcelo","family":"Sald\u00edas O'Hrens","sequence":"first","affiliation":[{"name":"Departamento de Fonoaudiolog\u00eda, Facultad de Medicina, Universidad de Chile 1 , Santiago,","place":["Chile"]},{"name":"Speech and Voice Research Laboratory, Faculty of Social Sciences 2 , , Tampere,","place":["Finland"]},{"name":"Tampere University 2 , , Tampere,","place":["Finland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9013-6830","authenticated-orcid":false,"given":"V\u00edctor","family":"M.
