Speech disorders, also known as dysarthria, are a very common consequence of stroke, affecting almost half of all survivors. A stroke can cause weakness in the facial muscles and vocal cords, making it difficult to speak fluently, clearly, or in complete sentences. While most people eventually recover, the process is often slow and frustrating and significantly impacts quality of life during rehabilitation.
Scientists at the University of Cambridge have been working to change this. Building on previous research, they have developed a wearable device called Revoice to help people with dysarthria communicate more naturally.
“When people suffer from dysarthria after a stroke, it can be extremely frustrating for them because they know exactly what they want to say, but physically can hardly say it because the signals between their brain and their throat have been disrupted by the stroke,” explains Prof. Luigi Occhipinti, one of the leaders of the research team.
