The speech of 102 patients with complete unilateral and bilateral cleft lip and palate and 40 noncleft subjects was analysed using the NORAM (Nasal Oral Ratio Meter) instrument. The results obtained were compared with the perceptual judgments made by experienced listeners. A significant correlation was found between the NORAM values and the listener judgments. The NORAM instrument can thus be used as a complement to listener judgments in assessing hypernasality. A discussion of the acoustic and phonetic aspects of the differences between the instrumental and perceptual results is presented.
使用NORAM（鼻口比率仪）仪器对102例单侧和双侧完全性唇腭裂患者以及40例非腭裂受试者的语音进行了分析。将所得结果与经验丰富的听众的感知判断进行了比较。发现NORAM值与听众判断之间存在显著相关性。因此，NORAM仪器可作为评估鼻音过重时听众判断的补充。本文还讨论了仪器测量结果与感知结果差异的声学和语音学方面。
