针对原发性声带震颤（EVT）的医学和行为干预研究显示，不同研究和参与者对声学和感知结果的影响不一致。远程声学和感知评估可以促进更大样本参与者的研究和重复测量，可以澄清治疗效果并确定最佳治疗候选者。此外，远程听觉和知觉评估可能允许临床医生监测客户的治疗反应和优化治疗方法。因此，本研究的目的是评估远程信号传输和记录的准确性，以评估EVT的声学和感知。使用计算模型进行EVT模拟，并使用本地和远程程序分别记录客户端和临床端录音。声学分析测量振幅和强度调制的程度和速率，以表示声带震颤的严重程度，并测量倒谱峰突出（CPPS），以表示语音质量。使用重复测量方差分析（ANOVA）对数据进行分析，记录作为受试者内因素，计算模型的性别作为受试者间因素。记录对强度调制速率有显著的主效应，记录和性别对强度调制程度、强度调制速率和CPPS有显著的交互作用。事后两两比较和效应量分析表明，记录程序对男性模拟的强度调制程度、男性和女性模拟的强度调制速率以及男性和女性模拟的CPPS影响最大。尽管禁用了所有已知的软件和计算机音频增强选项，并且具有稳定的以太网连接，但远程录音中的信号幅度衰减不一致，这对于具有呼吸语音质量的样本来说是最严重的问题，但也影响了具有典型和压制语音质量的样本。通过远程信号传输和记录，改变了与声音震颤和声音质量感知相关的声学测量。特别是，Zoom中的信号传输和记录改变了基于时间的强度调制估计和男性和女性EVT模拟的CPPS，以及基于震级的强度调制估计和男性EVT模拟。相比之下，信号传输和记录在Zoom中最小程度地改变了基于时间和幅度的调制估计，并模拟了男性和女性的EVT。因此，EVT的声学和感知评估应使用在参与者或客户端本地收集的录音进行，特别是在测量强度和CPP调制或估计声带震颤严重程度和语音质量时。制定在偏远地区收集当地录音的程序可以扩大治疗研究的数据收集并加强远程实践。
Studies on medical and behavioral interventions for essential vocal tremor (EVT) have shown inconsistent effects on acoustical and perceptual outcome measures across studies and across participants. Remote acoustical and perceptual assessments might facilitate studies with larger samples of participants and repeated measures that could clarify treatment effects and identify optimal treatment candidates. Furthermore, remote acoustical and perceptual assessment might allow clinicians to monitor clients’ treatment responses and optimize treatment approaches during telepractice. Thus, the purpose of this study was to evaluate the accuracy of remote signal transmission and recording for acoustical and perceptual assessment of EVT. Simulations of EVT were produced using a computational model and were recorded using local and remote procedures to represent client- and clinician-end recordings respectively. Acoustical analyses measured the extent and rate of fo and intensity modulation to represent vocal tremor severity and the cepstral peak prominence (CPPS) to represent voice quality. The data were analyzed using repeated measures analysis of variance (ANOVA) with recording as the within-subjects factor and sex of the computational model as the between-subjects factor. There was a significant main effect of recording on the rate of fo modulation and significant interactions of recording and sex for the extent of intensity modulation, rate of intensity modulation, and CPPS. Posthoc pairwise comparisons and analysis of effect size indicated that recording procedures had the largest effect on the extent of intensity modulation for male simulations, the rate of intensity modulation for male and female simulations, and the CPPS for male and female simulations. Despite having disabled all known software and computer audio enhancing options and having stable ethernet connections, there was inconsistent attenuation of signal amplitude in remote recordings that was most problematic for samples with a breathy voice quality but also affected samples with typical and pressed voice qualities. Acoustical measures that correlate to perception ofvocal tremor and voice quality were altered by remote signal transmission and recording. In particular, signal transmission and recording in Zoom altered time-based estimates of intensity modulation and CPPS with male and female simulations of EVT and magnitude-based estimates of intensity modulation with male simulations of EVT. In contrast, signal transmission and recording in Zoom minimally altered time- and magnitude-based estimates of fo modulation with male and female simulations of EVT. Therefore, acoustical and perceptual assessments of EVT should be performed using audio recordings that are collected locally on the participant- or client-end, particularly when measuring modulation of intensity and CPP or estimating vocal tremor severity and voice quality. Development of procedures for collecting local audio recordings in remote settings may expand data collection for treatment research and enhance telepractice.
