A soft, wearable neck device that translates silent throat muscle vibrations into audible speech was associated with improved communication fluency and higher patient satisfaction among stroke survivors with dysarthria in a small clinical study.
The device, Revoice, combines textile sensors with large language models (LLMs) to translate silent articulatory movements into full sentences. Unlike prior silent speech technologies, this wearable supports a continuous, natural flow of communication without pauses that disrupt conversation, a limitation of standard augmentative and alternative communication (AAC) devices.
Stroke patients who used the wearable device achieved low word- and sentence-level error rates, whereas optional artificial intelligence (AI)-assisted sentence expansion significantly improved fluency and emotional expressiveness. Patients also reported a greater sense of ease with communication and...
