The Acoustic Voice Quality Index version 03.01 (AVQI-3) and Acoustic Breathiness Index (ABI) hold potential due to their comprehensive assessment approach, incorporating diverse voice aspects. However, these tools still need to be validated in English-speaking populations. Methods: This study assessed the discriminatory accuracy and validity of AVQI-3 and ABI in 197 participants, including 148 with voice disorders. Voice samples were collected, followed by AVQI-3 and ABI calculations. Additionally, auditory-perceptual assessments were conducted by a panel of speech-language pathologists. Results: AVQI-3 and ABI effectively identified disordered voice quality, evidenced by high accuracy (AUCs: 0.84, 0.89), sensitivity, and specificity (thresholds: AVQI-3 = 1.17, ABI = 2.35). Strong positive correlations were observed with subjective voice quality assessments (rs = 0.72, rs = 0.77, p &lt; 0.001). Conclusions: The study highlights AVQI-3 and ABI as promising instruments for clinically assessing voice disorders in U.S. English speakers, underscoring their utility in clinical practice and voice research.<\/jats:p>","DOI":"10.3390\/jcm12247679","type":"journal-article","created":{"date-parts":[[2023,12,15]],"date-time":"2023-12-15T08:12:57Z","timestamp":1702627977000},"page":"7679","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Clinical Utility and Validation of the Acoustic Voice Quality and Acoustic Breathiness Indexes for Voice Disorder Assessment in English Speakers"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9511-6203","authenticated-orcid":false,"given":"Adri\u00e1n","family":"Castillo-Allendes","sequence":"first","affiliation":[{"name":"Department of Communicative Sciences and Disorders, Michigan State University, East Lansing, MI 48824, USA"},{"name":"Department of Communication Sciences and Disorders, University of Iowa, Iowa City, IA 52242, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana","family":"Codino","sequence":"additional","affiliation":[{"name":"Lakeshore Professional Voice Center, Lakeshore Ear, Nose & Throat Center, St. Clair Shores, MI 48081, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lady Catherine","family":"Cantor-Cutiva","sequence":"additional","affiliation":[{"name":"Department of Communicative Sciences and Disorders, Michigan State University, East Lansing, MI 48824, USA"},{"name":"Department of Communication Sciences and Disorders, University of Iowa, Iowa City, IA 52242, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3576-6770","authenticated-orcid":false,"given":"Charles J.","family":"Nudelman","sequence":"additional","affiliation":[{"name":"Department of Speech and Hearing Science, University of Illinois Urbana-Champaign, Champaign, IL 61820, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam D.","family":"Rubin","sequence":"additional","affiliation":[{"name":"Lakeshore Professional Voice Center, Lakeshore Ear, Nose & Throat Center, St. Clair Shores, MI 48081, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0086-8163","authenticated-orcid":false,"given":"Ben","family":"Barsties v.
