| Outline of Final Research Achievements |
For the purpose of supporting a speech communication of hearing impaired persons or deaf persons, we have developed a multi-modal type of wearable system that presented a visualized speech and a hearing aided speech sound, simultaneously. Since both of a speech analysis unit and an image synthesis unit have been implemented in the software engine based on C-language, we have revised those programs and designed a DSP program for real-time processing on a manufactured DSP board. In addition, after designing and manufacturing a portable type of DSP board, a real-time processing and its accuracy were verified under the offline condition. Generation and output of the hearing aid sound is easy to be implemented from our past research result. In order to establish the proposed whole system, we have left some problems of devising a display of the visualized speech image, because it has not yet completed an interface between the HDMI for image signal and the DSP system.
