New Wearable Device Translates Throat Muscle Movements into Speech for Voice Disorder Patients
-
A wearable, non-invasive device is developed to assist patients with voice disorders in communicating during recovery by detecting throat muscle movements and converting them into speech.
-
The device uses soft magnetoelastic materials and machine learning to accurately translate muscle movements into specific voice signals based on a pre-trained model.
-
Key features include high stretchability, quick response time, skin-like modulus for comfort, intrinsic waterproofing, and customizable user settings.
-
In tests on 8 subjects, the device achieved 94.68% accuracy in classifying sentences from muscle movements and outputting the corresponding pre-recorded voice signal.
-
This technology could significantly improve quality of life for those with vocal cord impairments by enabling speech during post-surgery and other recovery periods.
