AI-Powered Multilingual Content Localization Engine

The rapid growth of digital learning platforms has improved access to educational resources worldwide, but language barriers still limit accessibility, especially in multilingual countries like India where most online content is available in English. To address this issue, this paper introduces LearnBridge AI, a unified localization and content distillation engine designed to convert educational materials into more than 22 Indian and foregien languages while also generating concise summaries. The system uses a hybrid architecture combining local processing with advanced language models. Audio content is transcribed using a locally deployed OpenAI Whisper speech-to-text model to ensure data privacy. For multilingual translation, the system integrates Gemini 1.5 Flash, while local extractive summarization reduces latency and API costs. Implemented using Node.js, Python, and React.js, LearnBridge AI provides an efficient and scalable solution for multilingual educational accessibility.
