Abstract

Ultrasound Visual Biofeedback (U-VBF) uses medical ultrasound to image the tongue in real-time during speech. Clinicians can use this information to both assess speech disorders and as a biofeedback tool to guide children in producing correct speech. Ultrasound images of the tongue are thought to be relatively intuitive to interpret, however, there is no easy way of using the ultrasound to diagnose speech disorders, despite it having the potential to identify imperceptible errors which are diagnostically important. This manual describes how to use ultrasound for the assessment and treatment of speech sound disorders in children. It is designed to be used in combination with Articulate Instruments Ltd. Sonospeech software by clinical partners of the Ultrax2020 project. However, the basic principles and resources contained within this document will be of use to anyone interested in using ultrasound in the speech therapy clinic.
