Computer-controlled method for measuring articulatory activities
G. van der Giet · The Journal of the Acoustical Society of America · 1977
A computer on-line method for measuring articulatory activities is presented. Small receivers are attached to articulatory organs, recording their motion via electric voltages induced by external inhomogeneous electromagnetic fields. The signals, which are the electrical equivalents of the motion relative to a coordinate system, are subjected to automatic computer analysis. First, experiments have been performed and the results for some utterances are shown, demonstrating the abilities of the system. Moreover, as an example of automatic performance, lip-opening data are deduced.
