SRAVI lipreading app
SRAVI is a mobile app that brings a voice to the voiceless. Using just a mobile phone, SRAVI is able to convert your silent lip movement into text for others to understand. You simply mouth phrases into your phone's camera, using the app.
SRAVI helps you communicate with people in an efficient and natural way, using only lip movements. It can currently recognise up to 50 phrases, and it can be customised for different occasions.
SRAVI has been tested successfully in a pilot project at Lancashire Teaching Hospitals NHS Trust, and we are now starting trials with more NHS Trusts.
We are Liopa. We were incorporated in 2015 to commercialise more than 15 years of PhD research at Queen's University Belfast in the field of speech and image processing. Using this deep knowledge, we developed an automated lipreading solution. Our technology – rooted in machine learning and AI – can decipher what a person is saying from their lip movements alone.
Liopa is the first company to release commercially available VSR (Visual Speech Recognition) technology, with the first application being our SRAVI app (www.sravi.ai).
SRAVI is a simple lipreading application that requires just a smartphone. It is bringing a voice to the voiceless.
With SRAVI, we help patients who have lost the ability to speak, to communicate with their loved ones & carers. SRAVI is deployed onto a smartphone, and when pointed towards the patient, the app analyses their lip movements to decipher what they are trying to say. SRAVI is being trialled in Intensive Care units within the NHS.
SRAVI’s real-life usage is explained in the attached case studies from ICU Consultant Dr. Shondipon Laha and one of his patients – both from the Lancashire Teaching Hospitals NHS Trust.
Our lipreading technology can also be used in a range of other applications, including keyword spotting, active speaker detection, and silent communication – more can be found at www.liopa.ai.
