Just think: Can a person tell you his feelings and thoughts completely clearly without saying a single word? It sounds like a story from a movie, but it is now going to be true in the world of science. Scientists at the University of Cambridge and Beihang University have created an AI-powered intelligent throat device that will provide voice to millions of stroke patients who have lost the ability to speak. This small neckband named Revoice not only understands your lip movements, but also easily converts your feelings into words. Let us know how this magical gadget is going to change the world of medical science…
This is possible because of medical science and AI, and it can change the lives of patients who have difficulty speaking. Researchers from Cambridge University and Beihang University have created a high-tech device named Revoice. The device is designed for stroke survivors who suffer from dysarthria, a condition that causes difficulty speaking due to weakness or poor control of the speech muscles. In this condition, the patient’s brain knows what they want to say, but their throat muscles do not cooperate, making speech very difficult.
fits without any surgery
Usually, in such cases, patients need a chip or implant in the brain, but Revoice is a soft choker, a band worn around the neck. It is worn outside the neck and is completely non-invasive, which means it does not require any surgery or incisions.
How does this technology work?
This neckband has sensors that are so sensitive that they can detect even the smallest changes in the skin, such as changes as small as 0.1%. When the patient speaks words without making any sounds, the device records vibrations in the throat and the pulse of the carotid artery. This data from the device is then sent to two AI agents. The first agent combines broken words into a complete sentence, while the second understands the patient’s emotions and converts them into voice. The most important thing is that it processes data every 100 milliseconds, due to which the conversation seems completely natural.
Trial was conducted on patients
In tests conducted on 5 stroke patients, the device showed 95.8% accuracy in recognizing words and 97.1% accuracy in recognizing complete sentences. Its battery lasts all day, and it’s designed to be very comfortable for everyday use. Researchers believe that in future this technology will also prove beneficial for patients with Parkinson’s disease and motor neuron disease.
