The perceptual speech characteristics of a group of 20 severely closed head-injured (CHI) subjects were compared with those of a normal non-neurologically impaired control group matched for age and sex. The CHI subjects were found to be significantly less intelligible than the controls, and exhibited deficits in the prosodic, resonatory, articulatory, respiratory and phonatory aspects of speech production. The most frequently occurring deviant speech dimensions related to disturbances of prosody, resonance, articulation and respiration, with those deviant speech dimensions pertaining to phonation being less apparent in the speech of the CHI subjects. The findings are discussed in relation to the heterogeneity of the CHI population and the effects of CHI on neuromuscular function. The study highlights the need for accurate, instrumental physiological evaluation of the motor subsystems involved in speech production.
将一组20名重度闭合性颅脑损伤（CHI）患者的言语感知特征与一组年龄和性别匹配的正常非神经功能受损对照组的特征进行了比较。结果发现，CHI患者的言语清晰度明显低于对照组，并且在言语产生的韵律、共鸣、发音、呼吸和发声方面存在缺陷。最常出现的异常言语维度与韵律、共鸣、发音和呼吸障碍有关，而与发声相关的异常言语维度在CHI患者的言语中不太明显。结合CHI人群的异质性以及CHI对神经肌肉功能的影响对这些发现进行了讨论。该研究强调了对参与言语产生的运动子系统进行准确的仪器生理评估的必要性。
