News: Study finds that SRAVI lip-reading app makes patients’ lives easier
BELFAST, NORTHERN IRELAND – 20 November 2023 – A Real World Validation (RWV) study has been concluded in the North of England, comprising a joint effort between UCLAN, Liopa, and Lancashire Teaching Hospitals NHS Foundation Trust.
The study tested the efficacy of using the SRAVI lip-reading app in a real-world NHS hospital environment. Hospital clinicians have been using SRAVI since 2020 with their patients at Royal Preston Hospital’s ICU and high-dependency units. A small number of these clinicians completed a questionnaire to assess whether SRAVI is effective at enabling easier and more accurate communication between voice impaired patients, healthcare staff and carers/family members.

Vanderbilt Hospital (Nashville, TN, USA)
A feasibility study is now underway at Vanderbilt University Medical Center, located in Nashville, Tennessee, with Liopa’s SRAVI lipreading app. The study began in October 2022 and will run through the first half of 2023.
In this pilot trial, SRAVI's lipreading ability is being tested with patients who have undergone a total laryngectomy (TL), or complete removal of the voice box.
Altnagelvin NHS Hospital (Londonderry, Northern Ireland)
In collaboration with Queen’s University Belfast, a trial of SRAVI with ICU patients has been on-going since 2022. The project is led by investigator Professor Bronagh Blackwood and Staff Nurse/PhD Researcher Carla McClintock.
SRAVI will be offered to as many as 55 patients as a communications aid during their stay in critical care units.
The study will entail SRAVI being brought into Altnagelvin Hospital in Derry/Londonderry. Following this initial trial the study will commence at two Belfast sites, City Hospital and Royal Victoria Hospital, where it will be used with ICU patients as well as Head and Neck Cancer patients.
