The correlation between the nasalance score and the perceptual rating of several aspects of speech of speakers with velopharyngeal insufficiency (VPI) by six speech-language pathologists was evaluated.
The overall grade of severity, hypernasality, audible nasal emission, misarticulations, and intelligibility were rated on visual analog scales. Speech samples with a normal distribution of phonemes (normal text [NT]) and those free of nasal consonants (denasal text [DT]) of 43 patients with VPI were used. Mean nasalance scores were computed for the speech samples, and Spearman correlation coefficients were computed between the mean nasalance score and the five parameters of the differentiated rating.

The correlation coefficient between the mean nasalance and the perceptual rating of hypernasality ranged among judges from .31 to .56 for NT speech samples and .36 to .60 for DT speech samples. Only small differences were found between speech pathologists with and without expertise in cleft palate speech. The rating of the overall grade of severity appeared to correlate quite well with the rating of the intelligibility (r(NT) = .77, r(DT) = .79). Lower correlation coefficients, ranging from .34 to .71, were found between overall grade of severity and hypernasality, audible nasal emission, and misarticulations.
A low correlation between the nasalance and the perceptual rating of hypernasality was found. The parameter overall grade of severity appeared to be determined mainly by the parameter intelligibility. Expertise in rating of cleft palate speech does not guarantee a high correlation between instrumental measurement and perceptual rating.
评估六名言语病理学家对腭咽闭合不全（VPI）患者言语几个方面的鼻音评分与感知评级之间的相关性。
通过视觉模拟量表对严重程度、高鼻音、可闻鼻音、发音错误和可懂度的总体等级进行评级。使用了43名VPI患者的音素分布正常的言语样本（正常文本[NT]）和不含鼻辅音的言语样本（去鼻音文本[DT]）。计算言语样本的平均鼻音评分，并计算平均鼻音评分与差异评级的五个参数之间的斯皮尔曼相关系数。

对于NT言语样本，平均鼻音与高鼻音感知评级之间的相关系数在评判者之间为0.31至0.56，对于DT言语样本为0.36至0.60。在有腭裂语音专业知识和没有腭裂语音专业知识的言语病理学家之间仅发现微小差异。严重程度总体等级的评级似乎与可懂度的评级相关性很好（r(NT)=0.77，r(DT)=0.79）。在严重程度总体等级与高鼻音、可闻鼻音和发音错误之间发现较低的相关系数，范围从0.34至0.71。
发现鼻音与高鼻音感知评级之间的相关性较低。严重程度总体等级参数似乎主要由可懂度参数决定。腭裂语音评级方面的专业知识并不能保证仪器测量与感知评级之间有高度相关性。
