Braille Keyboard Voice Computer

This technology is capable of producing a project-based method for blind persons to learn Braille. Whatever system is currently in use is still an analogue system, but we are now using a digital method. This system includes input devices such as a keyboard with Braille dot language keys, as well as a keypad that is connected to the CPU (microcontroller). The microcontroller unit reads the data from the keypad and determines which keys are present. When the OK key is hit, a pre-recorded voice message from voice IC is activated. We can teach Braille students at a higher level and improve their learning by employing this technique. The AP33R voice module is appropriate for applications like telephones, Warnings about security and access control, museum narrations, and more each channel has a maximum capacity. Up to one minute of recorded voice and/or music, with a total recording time of eight minutes. Using the built-in microphone and the push-to-record button, recording is simple and quick.
