Abstract

Objective: To assess the concurrent validity and the diagnostic accuracy of the Acoustic Breathiness Index (ABI) in Brazilian Portuguese.

Methods: The counting numbers 1-20 and the vowel /a/ of 150 subjects were recorded (37 vocally healthy and 113 with dysphonia). The analyzed samples were the counting number 1-11 and 3 s of the sustained vowel. Nine voice specialists performed the perceptual judgment of the degree of breathiness. The Spearman Correlation and the receiver operating characteristic (ROC) curve were used to assess ABI's concurrent validity and diagnosis accuracy.

Results: Results from five listeners were chosen for the study analyses due to moderate and substantial intra-rater reliability (Cohen's Kappa values = 0.520-0.772) and moderate inter-rater reliability (Fleiss Kappa = 0.353). The ABI presented a high concurrent validity (r = 0.746); 55.6% of the breathiness vocal deviation can be explained by the acoustic analysis (r² = 0.556). The ROC curve presented good diagnostic accuracy (85.2%). At a threshold of 2.94, the sensitivity was 75.3% and the specificity was 93.4%.

Conclusion: The ABI is a valid tool for screening and patient's follow-up regarding breathy vocal qualities in the Brazilian Portuguese language.

巴西葡萄牙语的声学呼吸指数验证。

目的:评价巴西葡萄牙语患者声呼吸指数(ABI)的并发效度和诊断准确性。方法:记录150例(正常发声者37例，发声障碍者113例)的计数数1 ~ 20和元音/a/。分析的样本为持续元音的计数1-11和3s。九名声音专家对呼吸程度进行了感性判断。采用Spearman相关和受试者工作特征(ROC)曲线评价ABI的并发效度和诊断准确性。结果:选择了5名听者的结果进行研究分析，因为听者内部信度中等且相当高(Cohen's Kappa值= 0.520-0.772)，听者之间信度中等(Fleiss Kappa值= 0.353)。ABI具有较高的并发效度(r = 0.746);55.6%的呼吸性声偏可以用声学分析来解释(r2 = 0.556)。ROC曲线的诊断准确率为85.2%。阈值为2.94时，敏感性为75.3%，特异性为93.4%。结论:ABI是巴西葡萄牙语呼吸性声带质量筛查和随访的有效工具。

期刊介绍： Logopedics Phoniatrics Vocology is an amalgamation of the former journals Scandinavian Journal of Logopedics & Phoniatrics and VOICE. The intention is to cover topics related to speech, language and voice pathology as well as normal voice function in its different aspects. The Journal covers a wide range of topics, including: Phonation and laryngeal physiology Speech and language development Voice disorders Clinical measurements of speech, language and voice Professional voice including singing Bilingualism Cleft lip and palate Dyslexia Fluency disorders Neurolinguistics and psycholinguistics Aphasia Motor speech disorders Voice rehabilitation of laryngectomees Augmentative and alternative communication Acoustics Dysphagia Publications may have the form of original articles, i.e. theoretical or methodological studies or empirical reports, of reviews of books and dissertations, as well as of short reports, of minor or ongoing studies or short notes, commenting on earlier published material. Submitted papers will be evaluated by referees with relevant expertise.
