SuperTalker: Affordable Assistive Communication Device

This project is an initiative by the GEC Thrissur Ideator Student Team to design a low-cost assistive speech device for the National Institute of Physical Medicine and Rehabilitation (NIPMER). Inspired by the existing SuperTalker FeatherTouch device, our aim is to create an affordable alternative that promotes communication for individuals with speech disabilities.

Project Overview

The SuperTalker device provides a customizable interface for recording and playing back audio messages. It uses capacitive touch switches for user input, making it accessible for individuals with limited dexterity. Key features include:

• Customizable message grids: Supports multiple messages with symbol overlays for visual assistance.
• Feather touch interface: A modern, durable, and easy-to-use input method.
• APR33A3 audio playback IC: Enables high-quality, standalone audio storage and playback.
• Durable and portable design: Lightweight and robust, suitable for everyday use.

Key Features

• Low Cost: Designed with affordability in mind to increase accessibility.
• Customizable Messages: Record and store personalized audio messages for various use cases.
• FeatherTouch Input: Reed switchesreplace traditional buttons for enhanced usability.
• User-Friendly Design: Simple overlays and interfaces ensure ease of use for all age groups.

Technology Stack

Hardware

• APR33A3 audio IC
• Reed switches(e.g., TTP223)
• Rechargeable Li-ion battery

Software

• Firmware for interfacing touch inputs with message triggers

Enclosure

• Custom 3D-printed case for durability and aesthetics

Why This Project Matters

Communication is a basic human need, yet many assistive devices are prohibitively expensive. This project aims to bridge that gap by providing an affordable, high-quality alternative that empowers individuals with speech disabilities to express themselves effectively.
