Signed Language Translation into Afaan Oromo Text Using Deep-Learning Approach

A person who is unable to talk or hear anything can communicate via sign language. For those who have trouble hearing, sign language is a great way to communicate their thoughts and feelings. The vocabulary, grammar, and allied lexicons of sign language are well- defined. This study focuses primarily on Signed Afaan Oromo. The main issue in our society is the detection of Sign Language for the Afaan Oromo language. The construction of static word level, alphabet, and number translations into their equivalent Afaan Oromo text is the main focus of this thesis study. Video frames are used as the system's input, and Afaan Oromo text is used as the system's ultimate output. Data from 90 classes at the alphabet, number, and word level from five special needs instructors have been collected as part of an experiment and literature study to help answer the research objectives. Preprocessing, such as frame extraction, resizing, labeling, and splitting data using Roboflow, as well as the conversion of photos into Yolo model format, was done in order to train our model. Finally, based on the results of our experiment, we can quickly and effectively recognize and classify gestures using data sets of a medium size. The image, webcam, and video file's promising value and forecast results indicate that the yolov5 algorithm has a good chance of successfully detecting the sign in real-time. We trained and tested the model using a signed Afaan Oromo dataset. The YOLOv5s model was successful in obtaining accuracy of 90%, recall of 92.5%, mAP of 93.2% at 0.5 IoU, and a score of 71.5% at 0.5:0.95 IoU, which is suitable for real-time gesture translation.
