Abstract
Human vocalization relies on precise coordination of multiple muscles, yet existing language assistance devices are often bulky, uncomfortable, and costly. A multi-channel artificial throat system that simultaneously records electromyogram (EMG) signals from the suprahyoid, sternothyroid, and masseter muscles using ultrathin Au nanomesh electrodes has been presented. The nanomesh provides stable, conductive skin contact, increasing signal RMS from 0.3806 mV to 0.6074 mV. An all-flexible interface links the nanomesh to miniaturized circuits, improving wearability and signal integrity. For signal classification, BioSpeechNet, a deep learning framework that achieves over 94 % accuracy in recognizing words and phrases from transient EMG signals was introduced. Analysis reveals the masseter muscle contributes the most discriminative information for speech recognition. This work demonstrates a reliable nanomesh–circuit interface and highlights the potential of multi-muscle EMG for high-precision, wearable speech reconstruction.
期刊介绍:
Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas:
• Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results.
