| Abstract(in English) | A method for converting noisy sound into images to remove the noise has been proposed. We are attempting to remove train running noises and convert announcements into text in order to communicate train announcements to hearing disabilities. In the previous studies, the noise was removed by using U-Net with images converted from noisy sound. However, the quality of sound was not sufficient, since the restored sound was distorted. In this study, the optimal network model was built by adjusting conversion parameters of STFT and training parameters. The noise removal experiments from in-train announcements using data with multiple signal-to-noise ratios including low signal-to-noise ratios assuming in-train have been carried out. The recognition accuracy of noise-removed voice by voice recognition engine was improved, and the model with robustness could be built. |
