VOICE OF MUTE

Description:

The “Voice of Mute” project aims to bridge communication gaps for individuals with speech impairments by translating sign language into audible speech using an Arduino-based system. This project utilizes flex sensors, an Arduino microcontroller, and a sound playback module.

Flex sensors are attached to a glove worn by the user. These sensors detect the bending of fingers corresponding to various sign language gestures. The Arduino reads the resistance changes from the flex sensors and interprets the specific sign being made. Each unique combination of sensor readings correlates to a predefined sign language gesture stored in the Arduino’s program.

Upon recognizing a gesture, the Arduino triggers the sound playback module, which contains pre-recorded audio files for each gesture. The sound playback module plays the corresponding audio file through a speaker, converting the sign language gesture into spoken words. This real-time translation facilitates communication for individuals who are mute, allowing them to interact more effectively with those who do not understand sign language.

The project’s components include:

• Arduino microcontroller
• Flex sensors
• Sound playback module
• Speaker
• Power supply

By leveraging simple electronics and programming, this project provides an innovative, cost-effective solution to enhance communication for the speech-impaired, promoting inclusivity and understanding in diverse settings.
