Real-time Braille to Speech Converter - To allow blind and deaf people to live a more accesible life!

• Raspberry Pi booted on Raspbian OS
• Espeak
• Alsa
• An IDE for Python 2

Getting Alsa ready

sudo apt-get install alsa-utils
sudo amixer cset numid=0
sudo amixer cset numid=1

Getting Espeak

sudo apt-get install espeak

Our system currently accepts inputs by push buttons and numerical keypad inputs.

We have mapped the braille array to the numerical keypad in the following manner:

7 8
4 5
1 2

Each key corresponds to an entry in the braille array. In order to enter a letter, press the corresponding patterns. Use 3 to end a sentence, 9 to end a word, and 6 to end a letter.

Press the button corresponding to the dot in the braille array. There will be specific buttons for ending sentences, words, and letters.

To deploy this code on a server, we tried Google Cloud Platform for their Text-to-Speech api

• Espeak - Offline Text to Speech api
• Alsa - Sound Management System
• Raspberry Pi - as the main controller
• Python 2
