If the fetus can vocalize, how can we detect it?
In this paper, a method to detect the vocal activities of the fetus is reported. An estimation of the intensity and frequency of the voice was made on the assumption that the fetus can vocalize. Based upon these results, experiments to detect the voice were made. From the analysis of the results, it was made clear that the voice seemed to be buried in the noise and difficult to detect.
