An investigation of interference between electromagnetic articulography and electroglottography

Abstract

The present study tested whether there is cross interference between state-of-the-art electromagnetic articulography (EMA) and electroglottography (EGG) during the acquisition of kinematic speech data. In Experiment 1, we calibrated EMA sensors 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 talker and one female talker, with and without simultaneous EGG recording. Collectively, the results provide no evidence of signal artifacts in either direction, suggesting that current EMA and EGG technology can be combined to reliably assess laryngeal and supralaryngeal motor coordination in speech.
