This paper introduces two independent experiments in which perceptual prominent degree and stress type of syllables are labeled in a speech corpus containing 300 utterances. The perceptual prominent degree obtained in the first experiment provides convincing evidence for the consideration of distinguishing semantic stress and rhythmic stress in the second experiment. The final results show that (1) semantic stress is more prominent than rhythmic stress; (2) rhythmic stress tends to be allocated to the last syllable of the last prosodic word (or foot) in a semantic unit; (3) the location of semantic stress is difficult to be predicted from the prosodic structure of a sentence.
