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.).

VISUAL SPEECH RECOGNITION (VSR)

Liopa’s VSR – LipRead – is video only & not affected by poor audio quality and background noise.

IMPROVES ACCURACY

LipRead improves word accuracy in real-world/noisy environments to offer seamless, intuitive language-processing accuracy for enhanced voice user interface.

ENHANCED QUALITY & USABILITY

LipRead can enhance the quality and usability of the Voice UI in shared offices, on the move, across the production line or at home.

AI INTELLIGENCE

LipRead employs a proprietary Machine Learning approach using Deep Learning & can be ‘intelligently’ integrated with ASR technology using dynamic weighting algorithms.
