This paper describes a new method for coupling ultrasound images with tree-dimensional electromagnetic data, to recover larger parts of the tongue during speech production. The electromagnetic data is superimposed on ultrasound images after spatial and temporal calibration. Successful fusion results are presented on various speech sequences. A complete setup for evaluation of the electromagnetic system is further presented.
