| Outline of Final Research Achievements |
We developed infrastructures of speech analysis, modification, and synthesis based on interference-free representations of speech parametric representations. In addition to our STRAIGHT-based infrastructure, which is a defacto standard in speech research, we developed a set of new independent algorithms. We made these algorithms as open-source. We elaborated on building supporting tools for promoting academic research using STRAIGHT systems. In addition to these planned accomplishments, we also established application infrastructure based on WaveNet, which revolutionalized speech applications based on deep learning.
