What is Voice UI? Liopa’s Chief Technology Officer Dr Fabian Campbell-West introduces this fascinating and powerful technology.

Our video snapshot gives a brief, simple overview.

How is Voice UI applied? Liopa’s specialism in the cutting-edge field of Visual Speech Recognition has created three main applications for their products and expertise:-

  • Transforming Voice UI: Making everyday applications like virtual assistant, including Siri, Cortana and Alexa, in-vehicle voice control and smart home devices, ever better through improved accuracy. Liopa’s LipRead product uses visual reading and a proprietary machine learning approach for enhanced usability and quality.
  • Liveness Detection: LipSecure by Liopa brings real improvements to online and mobile User Authentication by confirming that a real person is present. Anti-spoofing technology asks a user to repeat an on-screen sequence of digits and is software-based for superb cost-effectivess.
  • Keyword Spotting: The power of the ability to identify occurrences of words/ phrases in video footage, bringing new capabilities to surveillance video analysis, broadcast monitoring and transcription.

Voice UI has become, of course, increasingly common and is an interface more and more people are becoming familiar with in their cars, homes and more. While Liopa’s work to enhance the accuracy of Voice UI is extremely timely, it is the result of years of work on the subject of ‘visemes’ at Queen’s University Belfast.

The Liopa team includes proven expertise across commerce, software architectural design and development methodologies.
