最常用的评估方法是等长时间间隔(EAI)评分。最近,EAI量表用于评估鼻音过多的有效性受到了质疑。有效性的问题取决于要评级的维度的心理物理性质。本研究的目的是比较EAI评分和直接幅度估计(DME),以确定EAI评分是否是评估鼻音过长的有效方法。研究对象为20名腭裂修复术患者和鼻腔过长患者的语音样本。20名受试者参与了包括EAI量表、有模数的DME(DME-M)和无模数的DME(DME-WM)的听力任务。结果表明,EAI与DME-M、DME-WM之间呈曲线关系,提示EAI可能不是评价鼻音过长的有效方法,推荐使用DME。
Hypernasality is most commonly assessed using equal-appearing interval (EAI) scaling. Recently, the validity of EAI scaling for the evaluation of hypernasality has been questioned. The issue of validity rests on the psychophysical nature of the dimension to be rated. The purpose of this study was to compare EAI scaling with direct magnitude estimation (DME), in order to determine whether EAI scaling is a valid procedure for the evaluation of hypernasality. Connected speech samples from 20 individuals with repaired cleft palate and hypernasality were used. Twenty listeners undertook the listening tasks, which included EAI scaling, DME with modulus (DME-M), and DME without modulus (DME-WM). The results showed a curvilinear relationship between EAI and DME-M and between EAI and DME-WM, suggesting that EAI may not be a valid method for the evaluation of hypernasality; DME is recommended.
