Full description

This data set contains DmDx data files in .azk and .zil formats, which can be viewed by Notepad or other text editor program. The data are saved in Excel .xlsx format. The size for each .zil file is approximately 100 KB and .azk file is approximately 200 KB. Each Excel .xlsx file size is about 200 - 400 KB. The data were obtained through two perception experiments - Discrimination of Tones and Identification of Tones. Thai tones were used as testing stimuli in both experiments. Five groups of participants (Thai, Mandarin, Cantonese, Australian English and Swedish native speakers) participated in this study. In the Discrimination experiment participants had to discriminate two Thai tones i.e., say whether they are the same or different tones. In the Identification experiment Thai participants had to identify the Thai tones they heard, Mandarin and Cantonese participants had to map the Thai tones they heard with their native tones, and Australian English and Swedish participants had to map the Thai tones they heard with either 1) pitch contour symbols or 2) their intonations.
