However, the relation between imbalanced muscle activation and asymmetric vocal fold vibration is not well understood. This study introduces an asymmetric triangular body-cover model of the vocal folds, controlled by the activation of intrinsic laryngeal muscles, to investigate the effects of muscle imbalance on vocal fold oscillation. Various scenarios were considered, encompassing imbalance in individual muscles and muscle pairs, as well as accounting for asymmetry in lumped element parameters. The results highlight the antagonistic effect between the thyroarytenoid and cricothyroid muscles on the elastic and mass components of the vocal folds, as well as the impact on the vocal process from the imbalance in the lateral cricoarytenoid and interarytenoid adductor muscles. Measurements of amplitude and phase asymmetry were employed to emulate the oscillatory behavior of two pathological cases: unilateral paralysis and muscle tension dysphonia. The resulting simulations exhibit muscle imbalance consistent with expectations in the composition of these voice disorders, yielding asymmetries exceeding 30% for paralysis and below 5% for dysphonia. This underscores the versatility of muscle imbalance in representing phonatory scenarios and its potential for characterizing asymmetry in vocal fold vibration.<\/jats:p>","DOI":"10.1101\/2024.03.18.585590","type":"posted-content","created":{"date-parts":[[2024,3,20]],"date-time":"2024-03-20T15:40:14Z","timestamp":1710949214000},"source":"Crossref","is-referenced-by-count":1,"title":["Asymmetric triangular body-cover model of the VFs with bilateral intrinsic muscle activation"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9657-6183","authenticated-orcid":false,"given":"Jes\u00fas","family":"Parra","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5403-1852","authenticated-orcid":false,"given":"Carlos","family":"Calvache","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriel","family":"Alzamendi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6975-4247","authenticated-orcid":false,"given":"Emiro","family":"Ibarra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2773-1028","authenticated-orcid":false,"given":"Leonardo","family":"Sol\u00e1que","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8746-2491","authenticated-orcid":false,"given":"Sean D.","family":"Peterson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5581-4392","authenticated-orcid":false,"given":"Mat\u00edas","family":"Za\u00f1artu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"issue":"1","key":"2024032300100514000_2024.03.18.585590v1.1","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1121\/10.0009169","article-title":"Triangular body-cover model of the vocal folds with coordinated activation of the five intrinsic laryngeal muscles","volume":"151","year":"2022","journal-title":"The Journal of the Acoustical Society of America"},{"key":"2024032300100514000_2024.03.18.585590v1.2","first-page":"39","volume-title":"in Studientexte zur Sprachkommunikation: Elektronische Sprachsignalverarbeitung","volume":"2016","year":"2016"},{"key":"2024032300100514000_2024.03.18.585590v1.3","doi-asserted-by":"crossref","unstructured":"Birkholz, P. , Kr\u00f6ger, B.
