Abstract

Multipulse modeling of articulatory movements can provide a flexible and intuitive representation of the dynamic behavior of speech articulators. Such a representation can prove especially useful for the exploitation of the significant amounts of rich articulatory data that are collected via vocal tract imaging techniques such as real‐time MRI or x‐ray microbeam. Original multipulse LPC articulatory modeling studies only focused on a limited set of articulations by a single speaker as these were imaged using x‐rays. In this work, application of the multipulse modeling framework on the Wisconsin x‐ray microbeam speech production database is investigated. This database contains articulatory data, i.e., trajectories of points on the tongue, jaw, and lips during multiple articulations as well as hard palate tracings, from 57 speakers. The original measurements are converted to constriction degree measurements and it is …
