Abstract

Purpose: The purpose of this study was to analyse the relationship between automatic vowel articulation index (aVAI) and direct magnitude estimation (DME) among speakers with Parkinson's disease (PD) and healthy controls. We further analysed the potential of aVAI to serve as an objective measure of speech impairment in the clinical setting.

Method: Speech samples from native Finnish speakers were utilised. Expert raters utilised DME to scale the intelligibility of speech samples. aVAI scores for PD speakers and healthy control speakers were analysed in relationship to DME speech intelligibility ratings and, among PD speakers, disease stage utilising nonparametric statistical analysis.

Result: Mean DME intelligibility ratings were lower among PD speakers compared to healthy controls. Mean aVAI scores were nearly the same between speaker groups. DME intelligibility ratings and aVAI were strongly correlated within the PD speaker group. aVAI and DME intelligibility ratings were moderately correlated with disease stage as measured by the Hoehn and Yahr scale.

Conclusion: aVAI was observed to be a promising tool for analysing vowel articulation in PD speakers. Further research is warranted on the application of aVAI as an objective measure of severity of speech impairment in the clinical setting, with varying patient populations and speech samples.

帕金森病患者自动元音发音指数和语音清晰度听觉感知评估的比较研究。

目的：本研究的目的是分析帕金森病（PD）患者和健康对照者的自动元音发音指数（aVAI）和直接幅度估计（DME）之间的关系。我们进一步分析了aVAI在临床环境中作为言语障碍的客观衡量标准的潜力。方法：采用芬兰语母语者的语音样本。专家评分员使用DME来衡量语音样本的可懂度。使用非参数统计分析，分析了PD说话者和健康对照说话者的aVAI评分与DME语音清晰度评级的关系，以及PD说话者的疾病分期。结果：与健康对照组相比，PD扬声器的DME平均清晰度评分较低。说话者组之间的平均aVAI得分几乎相同。DME可懂度评分和aVAI在PD说话者组中具有很强的相关性。aVAI和DME可懂度评分与Hoehn和Yahr量表测量的疾病分期适度相关。结论：aVAI是一种很有前途的分析帕金森病患者元音发音的工具。有必要对aVAI在临床环境中的应用进行进一步的研究，将其作为衡量言语障碍严重程度的客观指标，患者群体和言语样本各不相同。

期刊介绍： International Journal of Speech-Language Pathology is an international journal which promotes discussion on a broad range of current clinical and theoretical issues. Submissions may include experimental, review and theoretical discussion papers, with studies from either quantitative and/or qualitative frameworks. Articles may relate to any area of child or adult communication or dysphagia, furthering knowledge on issues related to etiology, assessment, diagnosis, intervention, or theoretical frameworks. Articles can be accompanied by supplementary audio and video files that will be uploaded to the journal’s website. Special issues on contemporary topics are published at least once a year. A scientific forum is included in many issues, where a topic is debated by invited international experts.
