| Outline of Final Research Achievements |
A novel computer-assisted pronunciation training (CAPT) system has been developed by extracting articulatory features (AF) from speech to correct pronunciation. Research items focused are (1) improvement of AF extractor performance, (2) a subsystem to plot AF on a pronunciation map, (3) a subsystem to visualize learner’s articulatory gesture by comparing it with the correctly pronounced gesture, (4) a web-based CAPT system. Multiple linear mapping is applied for speech-to- phoneme recognition. In the web-based subsystems and the CAPT system, HTML5 that can handle audio and video data is introduced.
