摘　　要：Smoothed cepstral peak prominence(CPPs)is a measurement of the distance from the prominent cepstral peak to the linear regression line directly beneath it.Variations of CPPs data acquisition and analysis lead to the complexity of the clinical cut-off values,and there are no agreeable values for a specific voice disorder,such as hypokinetic dysarthria associated with Parkinson’s disease(PD).This study examined the CPPs in people with hypokinetic dysarthria associated with PD compared with healthy participants.Results demonstrated significant differences in speech tasks of sustained vowel and connected speech,with CPPs of connected speech more sensitive to dysphonia and gender difference in PD participants.Males in PD participants presented higher CPPs for sustained vowels and lower CPPs for connected speech than females.It is implied that a consistent clinical application protocol is necessary,and multiple acoustic measures are needed to ensure the accuracy of clinical decisions.平滑倒谱峰突出度(CPPs)是从突出倒谱峰到其正下方的线性回归线的距离的测量值。CPPs数据采集和分析的变化导致临床截止值的复杂性,并且对于特定的语音障碍(例如与帕金森病(PD)相关的运动性构音障碍)也没有令人满意的值。本研究检查了与PD相关的运动性构音障碍患者与健康参与者的CPP。结果显示,持续元音和连续语音的语音任务存在显著差异,连续语音的CPP对PD参与者的发音障碍和性别差异更敏感。PD参与者中的男性对持续元音的CPP高于女性,对连续语音的CPP低于女性。这意味着需要一致的临床应用方案,并且需要多种声学测量来确保临床决策的准确性。
