Speaking System for Deaf and Mute People with Flex Sensors

Recent advancements in technology have provided solutions to the communication of deaf and mute individuals. In this paper, the main objective is to provide easiness of communication and to implement an automatic speaking system for deaf and mute people. Communication is one of the most vital behaviors of a human. Every living being has its way of communication. What would it be like if humans could not talk or listen! The primary purpose of this project is to help people who cannot speak or hear. Since many of us cannot understand sign language, it will help people with disabilities to communicate with us and enable them to share everything. It will play an essential role in healthcare and education. This research study utilizes wearable gloves so that anyone can afford this easily. Four flex sensors, an accelerometer, a speaker module, gloves, an Arduino Uno, an LCD screen, a GSM 800L module, and lithium-ion rechargeable battery are used to develop an intelligent sign language recognition system for dumb people. Three rechargeable batteries were used to charge Arduino Uno, GSM, and speaker module. The sensor converts the detected execution load into a voltage and the Arduino Uno microcontroller detects this voltage. Finally, the detected signs are displayed on the LCD to display and pronounced verbally by the speaker.
