This paper describes a relationship between singing experience and laryngeal movement obtained by DeepLabCut software to investigate whether singing improves swallowing function. First, we track the coordinates of the laryngeal region in videos captured swallowing movements by using DeepLabCut. Second, we remove the unusual outliers, and perform linear interpolation and the normalization for the obtained coordinates. Third, we extracted the features such as RMS, peak width and swallowing time. Finally, we did Welch's test to them against two groups: one with singing experience and the other without singing experience. As a result, we found the feature with a significant difference, and that the singing experience affected the swallowing time.
