Abstract

Optical marker tracking integrated with electromagnetic articulometry was used to assess the movement extent of various points on (a) forehead skin and (b) points on a head-mounted apparatus, relative to a fixed point just above the upper incisors, and to compare the accuracy of the two different approaches to indexing head position during speech production. Both methods can provide a satisfactory index of head position. If skin-affixed markers are used, a minimum of 4 is recommended. Locations for optimal marker placement are identified.
