Abstract
Abstract. This paper focuses on aspects of ultrasound technology that have an
impact on the accuracy of this technique as an investigative tool for the study
of displacement, timing and movement of the tongue during speech. The paper
describes settings and elements in the design of ultrasound systems that can
affect spatial and temporal resolution and provides recommendations for how
to minimize distortion.
