The speakers in this corpus includes 11 Chinese language teacher, 11 Korean-speaking learners, 23 English-speaking learners and 86 Chinese heritage learners. Two paradigms, namely. "Variety Show" and "Debate" were designed to :fit in a 50-minute class. Speaker turns were marked with the video editing software ELAN to provide speaker codes and the precise time boundaries demarcating the hour-long recordings into speech turns. Based on the turn-markings, each snippet was displayed on a webpage to obtain a turnsychronized transcriptions. The corpus data were used for perceptual ratings and acoustic analysis of fluency and foreign accent, language assessment, speech recognition etc. The database is a prolific resource with speech samples for various research topics.
