Inter-rater agreement on Mandarin tone categorization: Contributing factors and implications

Poster Session 2aSC: Linking Perception and ProductionFactors that may/may not influence inter-rater reliability in assessing the accuracy of monosyllabic Mandarin tones produced by children and adults were examined in three experiments. Experiment 1 investigated inter-judge reliability in 2 groups of Mandarin-speaking adults--one group from China and the other from Taiwan-- on their categorization of filtered tones produced by adults and children. The results showed that the magnitude of inter-rater agreement was associated with the production accuracy of the speakers; the judges attained lower agreement in categorizing children\'s tones than adults\' tones. All judges who indicated that Mandarin was their strongest language and that they had learned and used Mandarin since birth performed similarly in their tone categorization regardless of their place of birth or country of residence. Similar results were found in Experiment 2, in which one group of the judges in Experiment 1 categorized tones produced by a new and larger group of adults and children, and in Experiment 3, in which a different group of adults categorized another new set of tones produced by different speakers. Implications of the findings in research design are discussed.
