听众对语音质量的评级的可靠性是语音研究中的一个中心问题，因为这种评级在临床上是首要的，也因为它们是评估其他衡量标准的标准。然而，广泛的文献回顾表明，在不同的研究中，评分者内部和评分者之间的信度波动很大。此外，我们自己的数据表明，不同的临床医生对嗓音粗糙度的评级差别很大，单一的声音通常会获得几乎所有可能的评级。目前还没有模型或理论框架来解释这些变化，尽管这样的模型可能会指导开发有效、有效和标准化的临床语音评估方案。我们提出了一个理论框架，将收视率的可变性归因于几个来源(包括收听者的背景和偏见、收集收视率的任务、收听者和任务之间的交互以及随机错误)。这一框架可能会指导新的临床语音和语音评估方案的开发，最终导致更可靠的感知评级和对病理性声音的感知质量的更好理解。
The reliability of listeners' ratings of voice quality is a central issue in voice research because of the clinical primacy of such ratings and because they are the standard against which other measures are evaluated. However, an extensive literature review indicates that both intrarater and interrater reliability fluctuate greatly from study to study. Further, our own data indicate that ratings of vocal roughness vary widely across individual clinicians, with a single voice often receiving nearly the full range of possible ratings. No model or theoretical framework currently exists to explain these variations, although such a model might guide development of efficient, valid, and standardized clinical protocols for voice evaluation. We propose a theoretical framework that attributes variability in ratings to several sources (including listeners' backgrounds and biases, the task used to gather ratings, interactions between listeners and tasks, and random error). This framework may guide development of new clinical voice and speech evaluation protocols, ultimately leading to more reliable perceptual ratings and a better understanding of the perceptual qualities of pathological voices.
