| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Conventional automatic subtitle generation systems based on speech recognition do not take into account paralinguistic information such as emotions included in speech, so it is difficult to understand the content of speech containing sarcastic expressions or polysemous words from subtitles alone. In such cases, it would be effective to generate subtitles that visualize the emotions contained in speech using fonts and colors. For this reason, we have previously studied a method to generate font subtitle images from speech recognition and speech emotion recognition results using image transformation with GAN, but it became clear that it is difficult to express complex emotions only with fonts. In this study, we propose a method to visualize emotions using not only fonts but also colors, by capturing emotions in a two-dimensional valence-activation space and creating a colormap in the emotion space based on Russell's circumplex model and Plutchik's wheel of emotions. We conducted multi-task training on three types of speech recognition, categorical emotion recognition, and valence-activation estimation using speech from the IEMOCAP dataset, and experimented with generating colored subtitles from speech using the created colormap. | |
