Previous studies on phonetics and stance-taking mainly focused on non-tonal languages. In this study, we found that tone variation could affect the perception of stance information. The study includes a production experiment and a perception experiment which is aimed to evaluate the stance polarity and stance strength. When the tone was nearer to its citation form as its duration got longer, the participants were more likely to identify the stance information as positive or negative. This gives us insight that there may be a express-inference process during the perception of stance-taking.
