Acoustics might have the potential to objectify voice quality (eg, hoarseness and breathiness). The Acoustic Voice Quality Index (AVQI) and the Acoustic Breathiness Index (ABI) revealed sufficient valid and reliable results in the evaluation of voice quality. The aim of the present study is to validate the recent version of AVQI 03.01 and ABI in their internal validation. The responsiveness of change is evaluated on the hoarseness and breathiness severity after voice therapy.
In total, 84 voice samples of continuous speech and sustained vowel [a:] before and after a voice therapy were used. All 42 subjects presented organic and nonorganic voice disorders and various degrees of dysphonia severity before and after behavioral voice therapy. The voice samples were judged by three voice experts using the RBH-scale, which is based on the GRBAS-scale.
The intra-rater reliability was high for hoarseness (mean kappa = 0.76) and breathiness (mean kappa = 0.69).The inter-rater reliability was lower for both voice quality characteristics and ranged between kappa = 0.27 to 0.29. A strong correlation was identified between the perceived rating of hoarseness and breathiness and AVQI and ABI before and after voice therapy (r = 0.715, p < 0.01, and r = 0.712, p < 0.01, respectively). Additionally, no significant differences were revealed.
The present results showed that AVQI version 03.01 und ABI had a high internal validity to assess voice changes after voice therapy. AVQI and ABI are two valid and robust voice measures to objectify hoarseness and breathiness.
声学可能具有使嗓音质量（如嘶哑和气息声）客观化的潜力。声学嗓音质量指数（AVQI）和声学气息声指数（ABI）在嗓音质量评估中显示出足够有效且可靠的结果。本研究的目的是在内部验证中对最新版本的AVQI 03.01和ABI进行验证。在嗓音治疗后，根据嘶哑和气息声严重程度评估变化的反应性。
总共使用了84份嗓音样本，分别为嗓音治疗前后的连续语音和持续元音[a:]。所有42名受试者在行为嗓音治疗前后均呈现出器质性和非器质性嗓音障碍以及不同程度的发声困难严重程度。嗓音样本由三位嗓音专家使用基于GRBAS量表的RBH量表进行评判。
对于嘶哑（平均kappa = 0.76）和气息声（平均kappa = 0.69），评分者内信度较高。对于这两种嗓音质量特征，评分者间信度较低，kappa值在0.27至0.29之间。在嗓音治疗前后，嘶哑和气息声的感知评分与AVQI和ABI之间均发现有强相关性（分别为r = 0.715，p < 0.01，以及r = 0.712，p < 0.01）。此外，未发现显著差异。
目前的结果表明，AVQI版本03.01和ABI在评估嗓音治疗后的嗓音变化方面具有较高的内部效度。AVQI和ABI是两种有效且可靠的嗓音测量方法，可使嘶哑和气息声客观化。
