Item Embargo Voice Agentic Smart Reader Application In Sinhala and Tamil For Visually Impaired People(Institute of Electrical and Electronics Engineers Inc., 2026-05-22) Siriwardana B.J.A; Hewagama A.D; Aluwihare M.C; Sharumathan M; Weerasinghe, M; Abeywardhana, LThis paper proposes an intelligent smart reading system to improve access to documents, news articles, and printed content for visually impaired and reading-challenged users, particularly in low-resource languages such as Sinhala and Tamil. Although recent advances in computer vision, speech processing, and large language models have enabled effective document understanding, existing systems often operate independently and provide limited support for non-visual navigation, interactive information access, and expressive audio output. The proposed system integrates four main components into a unified framework. First, a voice-guided navigation module enables users to capture documents without visual assistance by providing real-time audio guidance, ensuring proper alignment and reliable image acquisition for text recognition. Second, a Tamil document understanding and question answering module processes document content and supports accurate, context-aware information retrieval using a retrieval-based approach, while also providing personalized content recommendations. Third, a voice-assisted Sinhala reading module allows users to navigate documents and access information using natural voice commands and semantic processing. Finally, an emotional text-to-speech module generates expressive speech in Sinhala and Tamil, improving the naturalness and clarity of audio output. Experimental results demonstrate that the proposed system improves document capture accuracy, navigation efficiency, information retrieval performance, and speech quality. Overall, the system provides a practical, accessible, and user-centered solution for intelligent document interaction in underrepresented languages.Publication Embargo Machine Learning-Based Smart Shopping for Visually Impaired(2021 3rd International Conference on Advancements in Computing (ICAC), SLIIT, 2021-12-09) Nagenthiran., N.; Priyanha, P.; Nirosha, S.; Vivek., J.; De Silva, H.; Sriyaratna, D.There are diverse applications built for the e- commerce platform, each with its own set of advantages. All goods should be relevant to all members of society around the world, but there are people with unique needs who should be considered when technology advancements are made for the common good. People who are blind require particular attention since they require assistance from others. For this research, we referred to several studies with comparable goals and approaches, which our group closely examined to enhance our study and outcomes, and which were highlighted when relevant work was discussed. The purpose of this study is to provide accessibility for all members of society, including the blind, as well as location-based solutions for consumers. These include voice navigation through the app, product suggestions, offering quick paths to the shop location by comparing existing algorithms for identifying short paths and providing a function to give voice feedback. This paper thoroughly examined the findings and provided appropriate evidence to support the answer to the challenge mentioned above. This sort of research will have a beneficial influence on our IT companies' consideration for those who live with specific needs that technology may help them meet.Publication Embargo Machine Learning-Based Smart Shopping for Visually Impaired(2021 3rd International Conference on Advancements in Computing (ICAC), SLIIT, 2021-12-09) Nagenthiran, N.; Priyanha, P.; Nirosha, S.; Vivek, J.; De Silva, H.; Sriyaratna, D.There are diverse applications built for the e- commerce platform, each with its own set of advantages.
