中文摘要
目的： 本探索性研究考察了在北京居住时间不同的女大学生在冬季是否存在主观嗓音症状、基线声学特征以及对喉部轮替运动嗓音负荷任务（LDDK-VLT）的声学反应差异。
方法： 在北京语言大学招募了41名年龄18-21岁的不吸烟女本科生，分为新近到达者（n = 16）、中间居住者（n = 14）和本地对照者（n = 11）。在基线（t0）、LDDK-VLT后即刻（t1）以及15分钟安静休息后（t2）进行声学录音。测量指标包括最长发声时间（MPT）、嗓音障碍严重指数（DSI）、基频（F0）、强度、基频微扰（Jitter）、振幅微扰（Shimmer）、谐噪比（HNR）和平滑倒谱峰值突出（CPPS）。参与者在所有录音后完成嗓音障碍指数-10（VHI-10）和嗓音疲劳指数（VFI）。分析了组间差异、声学变化评分、问卷-声学关联以及纵向声学轨迹。
结果： 新近到达者的VHI-10和VFI因子1得分在数值上高于本地对照者，但在错误发现率（FDR）校正后，没有问卷或基线声学测量在组间存在显著差异。变化评分分析显示，休息后Jitter（自由言语）变化存在未校正的组间差异，但该差异未通过FDR校正。线性混合效应模型显示，MPT、DSI、强度（朗读）、强度（自由言语）、Shimmer（朗读）、CPPS（朗读）和CPPS（自由言语）存在显著的校正后时间效应。校正后，没有组主效应或组×时间交互作用保持显著。问卷-声学关联为探索性分析，未通过校正。
结论： LDDK-VLT引起了可测量的时间依赖性声学变化，而校正后，北京居住时间并未显著调节纵向声学轨迹。主观评分和部分声学变化中的描述性模式提示，居住时间可能与嗓音状态和恢复相关，但需要更大规模且直接评估环境暴露的研究。
英文摘要
OBJECTIVES: This exploratory study examined whether female university students with different residence durations in Beijing differed in subjective voice symptoms, baseline acoustic characteristics, and acoustic responses to a laryngeal diadochokinesis vocal loading task (LDDK-VLT) in winter.
METHODS: Forty-one nonsmoking female undergraduate students aged 18-21 years were recruited at Beijing Language and Culture University and divided into recent arrivals (n = 16), intermediate residents (n = 14), and local controls (n = 11). Acoustic recordings were obtained at baseline (t0), immediately after the LDDK-VLT (t1), and after a 15-minute quiet rest (t2). Measures included Maximum Phonation Time (MPT), Dysphonia Severity Index (DSI), Fundamental Frequency (F0), Intensity, Jitter, Shimmer, Harmonics-to-Noise Ratio (HNR), and Smoothed Cepstral Peak Prominence (CPPS). Participants completed the Voice Handicap Index-10 (VHI-10) and Vocal Fatigue Index (VFI) after all recordings. Group differences, acoustic change scores, questionnaire-acoustic associations, and longitudinal acoustic trajectories were analyzed.
RESULTS: Recent arrivals showed numerically higher VHI-10 and VFI Factor 1 scores than local controls, but no questionnaire or baseline acoustic measure differed significantly across groups after false discovery rate (FDR) correction. Change-score analyses showed an uncorrected group difference for post-rest Jitter (free speech) change, but this did not survive FDR correction. Linear mixed-effects models showed significant corrected time effects for MPT, DSI, Intensity (reading), Intensity (free speech), Shimmer (reading), CPPS (reading), and CPPS (free speech). No group main effect or Group × Time interaction remained significant after correction. Questionnaire-acoustic associations were exploratory and did not survive correction.
CONCLUSIONS: The LDDK-VLT elicited measurable time-dependent acoustic changes, whereas residence duration in Beijing did not significantly moderate longitudinal acoustic trajectories after correction. Descriptive patterns in subjective scores and selected acoustic changes suggest that residence duration may be relevant to voice status and recovery, but larger studies with direct environmental exposure assessment are needed.
