发现语音评估中单一清晰度指标足以监测头颈癌患者治疗效果。
Relationship between objective and subjective perceptual measures of speech in individuals with head and neck cancer
- 通过主观评分与客观声学数据对比，分析语音特征关联性。
- 清晰度、发音和嗓音质量的主观评价与客观测量高度相关。
- 临床监测中可用单一清晰度指标替代多维评估，节省时间。
有意义的语音评估在临床语音学和治疗监测中至关重要。本研究在大规模头颈癌（HNC）数据集上考察了感知性语音评估与客观声学测量之间的关联。训练过的听评者对语音的可懂度、发音清晰度、嗓音质量、发声、语速、鼻音化及背景噪音进行评分。结果显示，主观可懂度、发音清晰度和嗓音质量之间存在强相关性，可能源于该人群语音症状的共同成因。客观可懂度和语速测量与主观评价一致。研究结果表明，在接受同步放化疗的头颈癌患者临床监测中，使用单一可懂度指标已足够。
原文摘要 · Abstract (English)
Meaningful speech assessment is vital in clinical phonetics and therapy monitoring. This study examined the link between perceptual speech assessments and objective acoustic measures in a large head and neck cancer (HNC) dataset. Trained listeners provided ratings of intelligibility, articulation, voice quality, phonation, speech rate, nasality, and background noise on speech. Strong correlations were found between subjective intelligibility, articulation, and voice quality, likely due to a shared underlying cause of speech symptoms in our speaker population. Objective measures of intelligibility and speech rate aligned with their subjective counterpart. Our results suggest that a single intelligibility measure may be sufficient for the clinical monitoring of speakers treated for HNC using concomitant chemoradiation.
