Article Synopsis
- Braille is a tactile writing system for the visually impaired, using raised dots arranged in cells, while Amharic is Ethiopia's official language spoken by over 100 million people.
- To improve written communication between sighted and visually impaired individuals in Amharic, deep learning models like CNN and BiLSTM have been applied to create Optical Braille Recognition (OBR) systems, though challenges remain due to the script's complexity.
- This study introduced a new deep learning model that achieved a Character Error Rate of 7.81% on Amharic braille, and released a free dataset for researchers to enhance future OBR technologies.
