已经进行了许多主观实验来开发客观的语音清晰度测量，但新型冠状病毒的爆发使得在实验室中进行实验变得困难。一种解决方案是使用众包进行远程测试;然而，由于我们无法控制收听条件，因此尚不清楚结果是否完全可靠。在这项研究中，我们比较了从远程和实验室实验中获得的语音清晰度分数。结果表明，远程实验的言语接收阈值（SRT）的均值和标准差（SD）均高于实验室实验。然而，在整个语音增强条件下的SRT的方差显示出相似性，这意味着远程测试结果可能与实验室实验一样有用，以制定客观的措施。我们还表明，练习会话分数与SRT值相关。这是在进行主要测试之前的先验信息，并且对于数据筛选以减少SRT分布的变异性是有用的。版权© 2021 ISCA.
Many subjective experiments have been performed to develop objective speech intelligibility measures, but the novel coronavirus outbreak has made it difficult to conduct experiments in a laboratory. One solution is to perform remote testing using crowdsourcing;however, because we cannot control the listening conditions, it is unclear whether the results are entirely reliable. In this study, we compared the speech intelligibility scores obtained from remote and laboratory experiments. The results showed that the mean and standard deviation (SD) of the remote experiments’ speech reception threshold (SRT) were higher than those of the laboratory experiments. However, the variance in the SRTs across the speech-enhancement conditions revealed similarities, implying that remote testing results may be as useful as laboratory experiments to develop an objective measure. We also show that practice session scores are correlated with SRT values. This is a priori information before performing the main tests and would be useful for data screening to reduce the variability of the SRT distribution. Copyright © 2021 ISCA.
