Abstract：
OBJECTIVE: Many employees, especially in voice-intensive professions, are under psychological stress at work, which is very difficult to objectify. The aim of the study was to analyze correlations between heart rate variability (HRV) parameters and objective voice function using weighted voice parameters (Dysphonia Severity Index [DSI]) in order to determine whether subjects with impaired vocal function show a predominance of sympathetic control during a vocal stress test.
METHODS: Prospective.
METHODS: Fifty-three people of working age were examined. After asking for sociodemographic, occupational, and voice-related data, the objective voice function was determined using the DiVAS voice diagnostics system, and a 20-minute vocal stress test was performed. The electrocardiogram was recorded using medilog AR12plus during the vocal stress test and in a 5-minute rest phase before and a 5-minute recovery phase after the test. HRV was analyzed using the Kubios HRV Premium software.
RESULTS: HRV was reduced during the vocal stress test compared to the resting and recovery phase. A Spearman correlation analysis showed significant correlations, particularly between the frequency-related HRV parameters and the DSI. The DSI correlated positively with the high frequency (HF) band (the relative power and the normalized unit). The DSI correlated negatively with the quotient between low frequency and HF and the low frequency normalized unit.
CONCLUSIONS: During a vocal stress test, adults in working age show a correlation between parameters of objective vocal function and parameters of HRV. The more impaired the objective vocal function, the higher the predominance of sympathetic activation under vocal stress. The voice can therefore be seen as a \"warning signal\" for the processes in the autonomic nervous system. The use of preventive strategies for stress management and for voice health appears to be particularly beneficial in vocally stressful occupations in order to achieve a positive effect on parasympathetic activity.

摘要：
目标：许多员工，特别是在语音密集型行业，在工作中受到心理压力，这很难客观化。该研究的目的是使用加权语音参数（发音障碍严重程度指数[DSI]）分析心率变异性（HRV）参数与客观语音功能之间的相关性，以确定嗓音功能受损的受试者是否表现出交感神经控制的优势。
方法：前瞻性。
方法：检查了53名工作年龄的人。在询问社会人口统计之后，职业,和语音相关的数据，使用DiVAS语音诊断系统确定目标语音函数，进行了20分钟的声乐压力测试。在声带压力测试期间以及测试前5分钟的休息阶段和测试后5分钟的恢复阶段，使用medilogAR12plus记录心电图。使用KubiosHRVPremium软件分析HRV。
结果：与静息和恢复阶段相比，在声带压力测试期间HRV降低。Spearman相关分析显示显著相关，特别是在频率相关的HRV参数和DSI之间。DSI与高频(HF)频带(相对功率和归一化单位)正相关。DSI与低频和HF与低频归一化单位之间的商呈负相关。
结论：在声乐压力测试中，工作年龄的成年人在客观声乐功能的参数和HRV的参数之间显示出相关性。客观声乐功能受损越多，声带压力下交感神经激活的优势越高。因此，声音可以被视为自主神经系统过程的“警告信号”。使用压力管理和语音健康的预防策略似乎在语音压力较大的职业中特别有益，以便对副交感神经活动产生积极影响。
