VisArtico: a visualization tool for articulatory data

Abstract : In this paper, we present VisArtico, a visualization tool for articulatory data acquired using the AG500 3D electromagnetic articulograph (EMA). This software allows displaying the positions of the EMA coils that are simultaneously animated with playback of the acoustic speech signal. It is also possible to display contours for the tongue and lips. The software helps to find the midsagittal plane of the speaker and offers data-based palate shape discovery. In addition, VisArtico allows labeling the articulatory data into phonetic segments. Our main goal is to provide an efficient, easy-to-use tool to visualize articulatory data for researchers working in the field of speech production.
