A Scottish university is hoping its research work will help create data to support new voice-recognition technologies.
Researchers from the University of Glasgow used a range of wireless sensing devices to analyse the muscle movement involved in speech. Twenty volunteers were asked to speak a series of vowel sounds, single words and entire sentences.
As participants spoke, radar technologies helped researchers image facial, tongue and larynx movements. Meanwhile, a laser system scanned skin vibrations and a camera captured deformations in the participant’s mouths.
The data was then validated by signal processing and machine learning techniques, building a detailed picture of the physical movements which allow people to form sounds.
