Development of Speech Recognition Mask Using Conductive Knitted Fabrics

Abstract

A speech recognition mask using conductive knitted fabrics enables voice input by mouth movements (silent speech). The conductive knitted fabric sewn into the mask acts as a flexible and highly sensitive strain sensor to measure the deformation of the mask caused by mouth movements, and the data obtained is used to estimate the silent voice. Using this mask, users can input voice without worrying about ambient noise or privacy issues. We conducted some experiments of voice recognition using the developed mask to demonstrate its effectiveness.
