Numerous patients who suffered from ALS, Alzheimer’s, or a stroke in the past face difficulties with moving the necessary muscles involved with speaking. Researchers from the University of Cambridge and Beihang University have created a wearable intelligent throat that has the potential to aid these patients, while targeting certain problematic areas in which older tech failed.
Firstly, the tech registers signals from throat vibrations and the carotid pulse. With the use of artificial intelligence, the machinery is able to convert these signals into words by breaking each word into tokens: individual smaller pieces of a larger sentence. With this technique, the AI is able to achieve a “4.2% word error rate, 2.9% sentence error rate”. The tech’s dual receptors allow for a more complex sentence formation than prior technology would have been able to achieve.
Indeed, the throat vibrations themselves transform into a short direct output. Thus, not much strain is put upon the speakers themselves. Next, the information received from the carotid pulse (emotional status) is given to the AI, which takes in the direct output, emotional level, and other environmental information (such as time, temperature, and climate) in order to produce an expansion of the short direct output. All of these computations are working in the form of a smart choker worn around the neck.
The older technology, while suitable for healthy users, produces fatigue and discomfort when worn by the patients. For example, one such common strategy is “1:1 mapping” in which every word the patient attempts to say is said with the technology. When communicating larger sentences, this technique can be unfeasible to patients, especially when put to larger tasks like full conversations. Furthermore, other systems have a time-window which forces users to wait a fixed period after every word before starting the next. Similarly to the earlier technique, this is also not practical for an everyday conversation.
This new technology provides numerous advantages for patients compared to older versions; moreover, the new development simultaneously proves that technology is constantly adapting and reworking itself to fill in the gaps and cracks of its predecessors. While this tech is a breakthrough currently and will transform the lives of many, it will also be modified in the future as the scientists adapt it to fit certain needs better.
