OVERVIEW – VSR APPLICATIONS

Liopa Visual Speech Recognition has three main application use cases.

Voiceless Speech Recognition

Communications aid for people who have lost the ability to speak:
  • Smartphone-based
  • Analyses lip movements to decipher phrases
  • Configurable vocabularies supported.

Transforming the Voice UI

Improving accuracy of speech recognition. Making voice-driven applications better:
  • Virtual Assistants – Siri, Cortana, Alexa
  • In vehicle Voice Activation
  • Smart Home device control.

Liveness Detection

Improved online and mobile User Authentication for enhanced security:
  • ensuring a real person is present
  • anti-spoofing for Facial Recognition
  • alternative to CAPTCHA.
Technology
with Liopa LipRead

Voice is now perceived as the future of the User Interface, ultimately replacing keyboard, mouse and touchpad.  Today’s voice-driven UIs (e.g. Alexa, Siri) depend on Audio Speech Recognition (ASR) technology.  But ASR accuracy & user experience can be severely impacted by background noise. Watch a quick overview.

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.
