Speech Visualisation Technology

Speech is the result of a highly complex and versatile system of co-ordinated muscular movements, and although perceptual assessment provides valuable information, instrumental observation can offer significant advantages.

Ultrasound Tongue Imaging (UTI)

Ultrasound Tongue Imaging (UTI)

LinguaSound 3D

Enhanced ultrasound tongue imaging system that incorporates contour tracking and 3D modelling for real-time visualisation of the tongue and hard-palate.

LinguaGraph Electropalatography (EPG) System

Electropalatography (EPG)


Detects tongue contact with the hard-palate during speech using a custom-made artificial palate that contains 62 electrodes embedded on its lingual surface.
