Technology
with Liopa LipRead
Liopa has created a novel, robust and convenient VSR platform, known as LipRead. Specifically, the Liopa technology can determine speech by analysing the movement of a user’s lips as they speak into a camera. These lip movements are known as visemes and are the visual equivalent of a phoneme or unit of sound in spoken language. The Liopa technology requires no additional hardware and will work on any device with a standard forward facing camera (e.g. smartphone, tablet, laptop, desktop, in-vehicle dashboard etc.).
