Abstract

This paper is meant to be an introduction to ultrasound as a suitable, efficient, non-invasive and relatively inexpensive method in studies of the physiology of speech production. Since 1826 to this very day, ultrasound has been used for various purposes and has gone through numerous modifications and improvements. Apart from being used diagnostically or therapeutically in the medical setting, as an imaging technique ultrasound is also adequate in speech production research for displaying internal structures of the vocal tract. Therefore, ultrasound plays a major role in physiology speech production research, speech disorders and articulatory speech synthesis. However, using ultrasound to image the vocal tract is a complex process which requires taking many crucial factors into consideration. Besides choosing which type of ultrasound machine and ultrasound probe to use, stabilizing subject’s head and the probe, annotation and intepretation of ultrasound data are also of very high importance. Acquiring complete image of particular section of the vocal tract is possible by using multiple physiological imaging techniques. It is considered that all imaging techniques should merge into one multichannel system. This kind of system could provide in-depth information about behaviours of various structures of the vocal tract. Ultrasound as an imaging technique is still experimental and in development. Due to its positive aspects and constant technological advancements we can assume that its usage in speech research will surely intensify.
