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.
