| Outline of Final Research Achievements |
In this research, we developed fundamental techniques for augmented speech production and its applications to break down existing barriers caused by physical constraints in our speech production. High-quality speech conversion methods to be effectively used in our physical speech production mechanism were successfully developed by combining a statistical approach capable of generating high-quality converted speech and a speech production modeling approach capable of intuitively controlling converted speech by manipulating movements of speech organs. Moreover, we developed various applications of the augmented speech production techniques, such as a speaking aid technique towards restoration of lost voices, a foreign speech generation technique while keeping speaker identity, and a telecommunication technique using body-conducted speech.
