目的：探讨语音共识听觉知觉评价（CAPE-V）中连接语音刺激对倒谱/频谱声学测量的影响。患者和方法：本研究分析了20名寻求发声障碍治疗的参与者的录音。参与者在舒适的音调和音量下阅读来自CAPE-V的6句刺激。从每个句子录音中获取倒谱峰突出（CPP）及其标准差、高低谱比（LH和LHsd）及其标准差以及语音障碍的倒谱谱指数（cepstral spectral Index）的多参数测量值并应用于分析。结果：句子类型对CPP、LH和LHsd的测量存在显著的主效应。事后两两比较显示，“We were away a year ago”这句全音句子对CPP的影响最大。对于LH和LHsd的测量，大多数比较的句子效应显著。结论：来自CAPE-V的连接语音刺激对倒谱/频谱声学测量的影响存在差异。这些发现支持了在临床评估中使用各种CAPE-V刺激的基本原理，并表明需要进一步的研究来为临床实践提供信息。
Objective: To investigate the effect of connected speech stimuli from the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) on cepstral/spectral acoustic measurements. Patients and Methods: Recordings from 20 participants seeking treatment for dysphonia were analyzed in this study. The participants read the 6 sentence stimuli from the CAPE-V at a comfortable pitch and loudness. Acoustic measures of cepstral peak prominence (CPP) and its standard deviation, the low-to-high spectral ratio and its standard deviation (LH and LHsd) and the multiparametric measure Cepstral Spectral Index of Dysphonia were acquired from each sentence recording and applied to analyses. Results: A significant main effect for sentence type was present on the measurements of CPP, LH and LHsd. Post hoc pairwise comparisons revealed the most robust effect on CPP from the all-voiced sentence ‘We were away a year ago'. For the measures of LH and LHsd, sentence effects were significant for the majority of comparisons. Conclusion: The connected speech stimuli from the CAPE-V affected cepstral/spectral acoustic measurements differentially. These findings support the rationale for using the various CAPE-V stimuli during clinical assessment, and indicate the need for further investigations to inform clinical practice.
