Congratulations to Dr. Ratree Wayland and her collaborators, Matthew Masapollo, Jessica Goel, Rahul Sengupta, Allen Shamsi, and Karen W. Hegland (all University of Florida), on the publication of their most recent article, “An investigation of interference between electromagnetic articulography and electroglottography” in JASA Express Letters. Link to the article can be found here and abstract is below. Way to Ratree and co-authors!
The present study tested whether there is cross-interference between electromagnetic articulography (EMA) and electroglottography (EGG) during the acquisition of kinematic speech data. In experiments 1A and 1B, EMA sensors were calibrated with and without EGG electrodes present in the EMA field. In experiment 2, EMA was used to record lip, tongue, and jaw movements for one male speaker and one female speaker, with and without simultaneous EGG recording. Collectively, the results provide no evidence of signal artifacts in either direction, suggesting that EMA and EGG technology can be combined to reliably assess laryngeal and supralaryngeal motor coordination in speech.
