PurposeThe感知的后果率降低，增加声音强度，清晰的语音进行了研究，在扬声器与多发性硬化症（MS），帕金森氏病（PD），和健康controls. Methodsevente-eight扬声器阅读句子习惯，清晰，响亮，和缓慢的条件。句子被等同于峰值振幅，并与多说话者的胡言乱语混合呈现给听众。使用计算机化的视觉模拟量表，听众判断可懂度或语音严重性的操作定义在Sussman和Tjaden（2012）.ResultsLoud和清晰的，但不是缓慢的条件改善可懂度相对于习惯条件。除了PD组的大声条件外，言语严重程度没有改善到习惯性以上，并且在某些情况下相对于习惯性有所降低。清晰度和语音的严重程度是密切相关的，但混乱的扬声器的关系较弱，在明确和缓慢的条件与habitual.ConclusionsBoth清晰和响亮的语音显示承诺，提高清晰度和维护或改善语音严重程度的multitalker牙牙学语的扬声器与轻度构音障碍继发MS或PD，至少这些感知结构的定义和测量在这项研究中。虽然缩放的可懂度和语音严重程度重叠，但这些指标在记录治疗相关的语音变化方面似乎还具有一些单独的价值。
PurposeThe perceptual consequences of rate reduction, increased vocal intensity, and clear speech were studied in speakers with multiple sclerosis (MS), Parkinson's disease (PD), and healthy controls.MethodSeventy-eight speakers read sentences in habitual, clear, loud, and slow conditions. Sentences were equated for peak amplitude and mixed with multitalker babble for presentation to listeners. Using a computerized visual analog scale, listeners judged intelligibility or speech severity as operationally defined in Sussman and Tjaden (2012).ResultsLoud and clear but not slow conditions improved intelligibility relative to the habitual condition. With the exception of the loud condition for the PD group, speech severity did not improve above habitual and was reduced relative to habitual in some instances. Intelligibility and speech severity were strongly related, but relationships for disordered speakers were weaker in clear and slow conditions versus habitual.ConclusionsBoth clear and loud speech show promise for improving intelligibility and maintaining or improving speech severity in multitalker babble for speakers with mild dysarthria secondary to MS or PD, at least as these perceptual constructs were defined and measured in this study. Although scaled intelligibility and speech severity overlap, the metrics further appear to have some separate value in documenting treatment-related speech changes.
