| Abstract(in English) | Many subjective experiments have been performed to develop objective speech intelligibility measure. But COVID-19 has made it extremely difficult to conduct experiments in a laboratory. One of solutions is to perform remote testing by using crowd sourcing. It is not, however, clear whether the results are entirely reliable because we cannot control their listening conditions. In this study, we compared speech intelligibility results obtained by remote testing and two laboratory experiments. The results showed that the average and the standard deviation of speech reception threshold (SRT) of the remote testing were greater than those of the laboratory experiments. But the variation of the SRTs across the speech enhancement conditions were very similar between them. It implies that results of remote testing may be usable to develop the objective measure as well as those of laboratory experiments. We also show data reduction based on the practice score slightly improves the SRT values. The SRT prediction using the stepwise approximation with the generalized linear model extracted the practice score as solely correlated explanatory variable. It seems a good criterion for data selection although other factors should be investigated more. |
