Liopa’s specialism in the cutting-edge field of Visual Speech Recognition, and associated areas, 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.

The Liopa team includes proven expertise across commerce, software architectural design and development methodologies. The key Liopa’s specialist services – including Liopa LipRead – lies in facing down the fact that, say, voice control for apps can be affected by background noise reducing the accuracy of the end result. Instead, Liopa have used an AI-based core to decipher what the user is saying, removing the risk of audio noise
