Revised catalogue specifications of speech corpora with user-friendly visualization and search system

It is well known that speech corpora are indispensable to speech research; several data centers of speech corpora have been set up worldwide in order to meet this demand that serve as a repository for various speech corpora. However, they use different specification systems for their corpora, and so it is difficult for speech corpora users to compare and select suitable corpora. It would be more convenient for the users if each data center used a common specification system for describing its corpora. Based on this idea, we have already proposed a set of specification attributes and items as the first step towards standardization, but the scale of the retrieval system was limited. This paper introduces a revised version of the speech corpora specification attributes and items to be connected with the large-scale metadata database “SHACHI” combined with the “Concentric Ring View (CRV) System” to improve the user interface.
