The research provides a perception experiment which tests the claims made in the previous production experiment (Chang 2008). It tests the perception of isolated synthetic stimuli, in which the crucial acoustic parameters (i.e., F0 peak delay, initial F0, and syllable duration) have been systematically manipulated. The results are generally consistent with the acoustic data, by showing that those acoustic cues contribute to the perception of two tone contrasts. The stimuli tend to be identified as the R item if the F0 peak is later in the syllable and the initial F0 is lower while the F0 peak is earlier in the syllable and the initial F0 is higher. However, although all three factors were certainly different between the two tones in the acoustic data, the three factors did not equally contribute to the perception of tone contrast.
