Standardization of Speech Corpus

Speech corpus is the basis for analyzing the characteristics of speech signals and developing speech synthesis and recognition systems. In China, almost all speech research and development affiliations are developing their own speech corpora. We have so many different kinds numbers of Chinese speech corpora that it is important to be able to conveniently share these speech corpora to avoid wasting time and money and to make research work more efficient. The primary goal of this research is to find a standard scheme which can make the corpus be established more efficiently and be used or shared more easily. A huge speech corpus on 10 regional accented Chinese, RASC863 (a Regional Accent Speech Corpus funded by National 863 Project) will be exemplified to illuminate the standardization of speech corpus production.
