A compact, data-driven statistical model for identifying roles played by articulators in production of English phones using 1D and 2D articulatory data is presented. Articulators critical in production of each phone were identified and were used to predict the pdfs of dependent articulators based on the strength of articulatory correlations. The performance of the model is evaluated on MOCHA database using proposed and exhaustive search techniques and the results of synthesised trajectories presented.
