ULTRASOUND TONGUE IMAGING
Tangled Tongues
Using an Ultrasound Tongue Imaging (UTI) machine, visitors were able to view their own tongues in action when speaking.
Visitors were asked to say different words such as 'LEAF' and 'PEEL' and to compare what they saw on the UTI to images on a worksheet.
This was the most popular station at the event, with 55 visitors choosing it as their favourite activity on the feedback forms.
