Many subjective experiments have been performed to develop objective speechintelligibility measures . The novel coronavirus outbreak has made it verydifficult to conduct experiments in a laboratory . One solution is to performremote testing using crowdsourcing . Because we cannot control the listening conditions, it is unclear whether the results are entirely reliable . We also show that the practice session scores correlate with the SRT values. This is a priori information before performing the main testsand would be useful for data screening to reduce the variability of the data screening, the authors say . The results showed that the mean and standard deviation(SD) of remote experiments’ speech reception threshold (SRT) were higher than those of the laboratory experiments. However, the variance
