technology records tongues in action -->
ENP Newswire -
Release date- 20092013 - Researchers from five Scottish universities are using ultrasound and MRI technology to build a three dimensional visualisation of tongues in action during speech.
The 'Seeing Speech' website, launched today (
Ultrasound Tongue Imaging is a comparatively new technique that uses medical ultrasound machines to record an image of the surface of the tongue during speech. Coupled with Magnetic Resonance Imaging (MRI) technology, which images the entire vocal tract including the action of the larynx and the soft palate, academics have built a database of online recordings showing speakers' tongues moving inside their mouths during normal speech.
Also included in the resource is a video database showing accent differences in speech production across varieties of English, which will aid the study of accents and accent change.
The team, led by researchers at the
Currently, there are no such comprehensive resources that visualise what is happening inside the mouth when we speak. This means that students of linguistics only have access to snapshots of what is a dynamic process. 'Seeing Speech' provides access to ultrasound and MRI videos, presenting the tongue's movement at full speed and half speed to allow for detailed study.
'One problem encountered by phonetics teachers and students is that there is nothing out there that shows how speech sounds are actually formed. The only resources that we had to work with up to this point were static diagrams and models that break the vocal tract up into sections and provide a fragmented view of what are really synchronised, dynamic actions of the vocal organs.'
