Abstract: Some meaningful prosodic patterns can be usefully represented with pitch contours, however developing such descriptions is a labor-intensive process. To assist in the discovery of contour representations, visualization tools may be helpful. Edlund et al. 2009 proposed the superimposition of hundreds of pitch curves from a corpus to see the overall patterns. In this paper we refine and extend this method, and illustrate its utility in the discovery of a prosodic cue to back-channels in Chinese.
