The iTalkBetter app, developed by the Neurotherapeutics Group at University College of London’s Queen Square Institute of Neurology (and supported by the Wellcome Trust), has been shown by an NIHR-supported study to significantly improve speech for people with the language disorder aphasia.
Aphasia is commonly caused by a stroke, severe head injury or brain tumours and also has links to dementia (most notably primary progressive aphasia / frontotemporal dementia).
The app analyses speech in real time and provides feedback for the person using it. It allows the person to practise over 200 commonly used words in their own time and without limits. iTalkBetter will soon be made available to all suitable patients to use, with its primary audience being stroke survivors.
