title: Is markerless acquisition technique adequate for speech production?
abstract: In this study, the precision of markerless acquisition techniques have been assessed when used to acquire articulatory data for speech production studies. Two different markerless systems have been evaluated and compared to a marker-based one. The main finding is that both markerless systems provide a reasonable result during normal speech and the quality is uneven during fast articulated speech. The quality of the data is dependent on the temporal resolution of the markerless system.
