We outline a method for collecting simultaneous high-speed ultrasound and electromagnetic articulography (EMA) data using widely-available commercial hardware and software. Previous research demonstrates the utility of a simultaneous EMA-ultrasound set-up and reports the magnitude of probe rotation and displacement over an experimental session. We build upon this research by (1) combining systems with higher temporal and spatial accuracy than those previously used; (2) using a more principled method for temporal synchronisation; (3) reporting the effects of ultrasound on the accuracy of EMA tracking; (4) tracking probe movement using an alternative stabilisation method. Our system shows a high degree of temporal and spatial accuracy and can be easily implemented by other researchers.
