Description

Around seventy million people internationally have a stutter, a form of a fluency disorder. Some fluency assistance devices are available to the public, but most are highly expensive or unreliable. The Fluency Assistive Device (FAD) team seeks to assist a niche community of these individuals who currently rely on a device known originally as the Edinburgh Masker by partnering with Dave Germeyer. Utilizing his expertise in repairing the Edinburgh Masker, FAD is developing two new versions of the masker to increase its portability, functionality, and cost-effectiveness. The first is an update of the original called the Analog Masker (Version 1.1). A prototype of the Analog Masker v1.1 has been developed, tested and is currently being revised based on the results. Revisions include updating the layout of the board and finalizing the power supply circuitry. The second version, known as the Digital Masker (Version 1.0), will use a Bluetooth-enabled microcontroller to achieve masker functionality. Bluetooth audio output for the Digital Masker has been tested, and two algorithms have been created for the masking output. The supporting software for the Digital Masker is nearing completion. The schematic and the layout design have been started for future implementation of the hardware.
