Interactive visualization and search system for speech corpora

We have already reported a corpus similarity visualization method based on the corpus attribute using multidimensional scaling that makes it easy for users to utilize various speech corpora. In this paper, we present a revised visualization method that is based on a ring structure like a planisphere. By using only a mouse, a user can choose appropriate search keys for each of the multiple attributes and can easily filter information by adjusting the keys. Retrieved results are displayed inside the rings, and the user can filter and browse them in real time. This will facilitate efficient searching of the specific corpus that fits user's needs.
