It is commonly held that there exists some prosodic differences between standard Chinese and accented Mandarin. In this paper, a perceptual test was first made by filtering the signal above 500Hz to conceal the segmental information and make utterances meaningless. It is proven that people could identify Standard Chinese (SC) and Shanghai-accented Mandarin (ASH) only by the prosodic features. Then, we studied the word stress of disyllables in citation form and found the word stress distribution and its acoustic features are different between SC and ASH.
