Multimodal speech data base for research: M2TINIT (Japanese)

M2TINIT is a multi-modal data base which japanese speech and lip dynamic scene are recorded concurrently. It is developed and opened to the public by Takao Kobayashi laboratory (Interdisciplinary Graduate School of Science and Engineering, Tokyo Institute of Technology) and Kitamura & Tokuda laboratory (Department of Computer Science, Nagoya Institute of Technology. Currently, Tokuda & Lee laboratory) for promotion of multi-modal speech research. It has been used to researches that are generation of speech and lip dynamic scene and bimodal speech recognition.
