CMDMC: A Diachronic Digital Museum of Chinese Mandarin

Modern Chinese Mandarin has gone through near a hundred years, it is very important to store its representative sample in digital form permanently. In this paper, we propose a Chinese Mandarin Digital Multi-modal Corpus (CMDMC), which is a digital speech museum with diachronic, opened, crossmedia and sharable features. It has over 3460 hours video and audio files with metadata tagging. The materials, which were generated by the authoritative speakers (e.g. announcers at TV or radio station) with normality, are required samples if we can get them. Based on this resource, we also intend to analyze the syntactic correlations of prosodic phrase in broadcasting news speech, and compare the phonetic and prosodic features in movie dialogues among several same-name movies in different historical eras.
