AB - We propose an open-source Artificial Intelligence (AI)-driven multilingual translation system that integrates real-time speech recognition and translation to resolve language barriers and misrecognition of technical terms in university lecture environments. The proposed system combines Whisper-based speech recognition, Bidirectional Encoder Representations from Transformers (BERT) and Levenshtein-distance based correction algorithm, and the DeltaLM multilingual translation model to automate the entire process from noise reduction and sentence refinement to context-aware translation and lecture script generation. In particular, a translation dataset containing domain-specific technical terms in the field of computer engineering is constructed and fine-tuned to improve translation precision in specialized domains. Experimental results show that the Word Error Rate (WER) decreases from 9.2 % to 4.7 %, achieving an improvement of approximately 51 %, while the average Bilingual Evaluation Understudy (BLEU) score increases from 56.3 to 60.2, corresponding to a 6.9 % performance gain. These results confirm that the proposed system achieves consistent translation quality improvements across all language pairs in academic lecture scenarios.
