What is this?

Contour Clustering gives you a graphical user interface to automatically get:
- time-series f0 measures
- interpolated, extrapolated, smoothed, and error-free f0 contours
- time-series intensity measures
- duration measures
- several speaker-correction methods
- several f0 contour representations (scaled, first derivative, principal components)
- cluster analyses on any of the chosen acoustic measures
- several clustering settings (distance metrics, linkage criteria)
- evaluations of the optimal number of clusters
- data (.csv) for further (manual) analysis, including graphs and tables

What Contour Clustering needs from you:
- a prosodic research question
- segmented speech (.wav/.mp3 and .textgrid)
- R and R Studio installed
