This study aims to validate a multiparameter analysis tool, the Acoustic Breathiness Index (ABI), for quantification of breathiness in the speaking voice, including both sustained vowels and continuous speech. One hundred and eight speakers with dysphonia (28 M, 80 F, mean age 50, SD 15.4 years) and 87 non-dysphonic controls (18 M, 69 F, mean age 42, SD 14 years) volunteered as participants. They read a standard text and sustained vowel \/a:\/. Acoustic recordings were made using a head-mounted microphone. Acoustic samples were evaluated perceptually by nine voice experts of different backgrounds (speech therapists, vocologists and laryngologists). Breathiness (B) from the GRBAS scale was rated. Headphones were used in the perceptual analysis. The dysphonic and non-dysphonic speakers differed significantly from each other in the auditory perceptual evaluation of breathiness. A significant difference was also found for ABI, which had a mean value of 2.26 (SD 1.15) for non-dysphonic and 3.07 (SD 1.75) for dysphonic speakers. ABI correlated strongly with B (rs = 0.823, p = 0.01). ABI\u2019s power to distinguish the groups was high (88.6%). The highest sensitivity and specificity of ABI (80%) was obtained at threshold value 2.68. ABI is a valid tool for differentiating breathiness in non-dysphonic and dysphonic speakers of Finnish.<\/jats:p>","DOI":"10.3390\/jcm12247607","type":"journal-article","created":{"date-parts":[[2023,12,11]],"date-time":"2023-12-11T14:12:51Z","timestamp":1702303971000},"page":"7607","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Validation of the Acoustic Breathiness Index in Speakers of Finnish Language"],"prefix":"10.3390","volume":"12","author":[{"given":"Elina","family":"Kankare","sequence":"first","affiliation":[{"name":"Department of Rehabilitation and Psychosocial Support, Logopedics, Phoniatrics, Tampere University Hospital, 33520 Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne-Maria","family":"Laukkanen","sequence":"additional","affiliation":[{"name":"Speech and Voice Research Laboratory, Tampere University, 33100 Tampere, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"311","DOI":"10.1044\/jshr.3902.311","article-title":"Acoustic Correlates of Breathy Vocal Quality: Dysphonic Voices and Continuous Speech","volume":"39","author":"Hillenbrand","year":"1996","journal-title":"J.
