语音声学分析通常是劳动密集型的、耗时的过程，其需要应用针对语音信号的各个方面定制的特质参数。这些过程限制了语音分析在临床实践以及应用研究和开发中的效率和实用性。在目前的研究中，我们分析了1120语音文件使用标准技术（个案手分析）;大约8周的时间完成的人员。然后将获得的结果与使用预设音高范围参数的几个自动分析脚本的分析输出进行比较。自动分析脚本将1680个语音样本的处理时间减少到小于2.5小时，并且当适当地选择音高窗口以考虑已知的群体差异（即，性别差异）。在将建议的设置应用于病态语音人群时应谨慎。
Voice acoustic analysis is typically a labor intensive, time consuming process that requires the application of idiosyncratic parameters tailored to individual aspects of the speech signal. These processes limit the efficiency and utility of voice analysis in clinical practice as well as applied research and development. In the current study, we analyzed 1120 voice files using standard techniques (case by case hand analysis); taking roughly 8 weeks of personnel time complete. The obtained results were then compared to the analytic output of several automated analysis scripts that made use of pre-set pitch range parameters. The automated analysis scripts reduced processing time of the 1680 speech samples to less than 2.5 hours and produced results comparable to the hand analysis when pitch window were appropriately selected to account for known population differences (i.e., sex differences). Caution should be exercised when applying suggested settings to pathological voice populations.
