What is a sound and speech interface? Liopa’s Chief Technology Officer Dr Fabian Campbell-West introduces how sound and speech can be used to interact with a device or machine.

Liopa’s specialists have taken sound and speech interface technology to create new standards of authentication technology.

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.

Thanks to changing interface technology becoming a daily fact of life for many users, asking ‘what is a sound and speech interface’ is something more and more people could not only explain but give examples to illustrate from their work or home life. This creates new challenges in that a business or organisation should closely examine the technology being used to prevent those who would seek to overcome the authentication used in these forms of UI.

Over ten years of research at Queen’s University Belfast, which led to the development of Liopa and its products, can now address this challenge.

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