This project aims to develop an intelligent voice assistant capable of real-time speech translation between French and English, while maintaining accuracy, con text, and meaning. The system is based on a Transformer architecture and combines tech niques such as Automatic Speech Recognition (ASR), Neural Machine Translation (NMT), and Text-to-Speech (TTS). Translation models have been trained on a custom dataset using f ine-tuning techniques to enhance performance in real-world use cases. The work also included a thorough evaluation of model performance using metrics such as accuracy and BLEU, which demonstrated promising results surpassing some common systems.
