| Abstract: | Generative Artificial Intelligence (GenAI) has achieved remarkable success in machine translation for high-resource languages; however, low-resource languages continue to suffer from poor translation quality due to limited parallel corpora, complex morphology, and cultural contextualization challenges. This research presents an enhanced generative translation framework tailored for low-resource languages by combining multilingual data augmentation, transformer-based architectures, and culturally aware optimization strategies. The proposed system leverages synthetic dataset generation through back-translation and large language model augmentation, followed by fine-tuning of mT5, mBART, and LLaMA models using parameter-efficient techniques such as LoRA and adapter layers. To reduce hallucinations and improve semantic fidelity, constraint-based decoding and reinforcement learning from human feedback are incorporated. Experimental evaluation conducted on multiple low-resource language pairs demonstrates significant performance gains over baseline models, achieving an average improvement of 8.7% in BLEU score, 6.3% in COMET, and 7.9% in BERTScore. Additionally, hallucination rates are reduced by approximately 35%, while human evaluation indicates improved grammatical correctness and cultural appropriateness in over 82% of translated samples. These results validate the effectiveness of the proposed framework in delivering accurate, context-aware translations for low-resource languages. The study contributes a scalable and deployable GenAI-based translation solution that promotes digital inclusion and supports linguistic preservation in multilingual ecosystems. |
