SMASH: a tool for articulatory data processing and analysis

Recent innovations in 3D motion capture technology such as electromagnetic articulography (EMA) are providing unprecedented access to the intricate movements of the articulators during speech production. Although these technological advances afford exciting opportunities for advancing the assessment and treatment of speech, they have presented new challenges associated with data collection, processing, and analysis. To address these challenges, we have standardized our EMA data collection protocols and developed a Matlab-based software tool, SMASH, for processing, visualizing, and analyzing speech movement data. The goal of the software is to advance research on speech production by improving the efficiency and reliability of speech movement analyses.
