Enhancing English Learning Environments Through Real-Time Emotion Detection and Sentiment Analysis

Educational technology is increasingly focusing on real-time language learning. Prior studies have utilized Natural Language Processing (NLP) to assess students' classroom behavior by analyzing their reported feelings and thoughts. However, these studies have not fully enhanced the feedback provided to instructors and peers. This research addresses this issue by combining two innovative technologies: Federated 3D-Convolutional Neural Networks (Fed 3D-CNN) and Long Short-Term Memory (LSTM) networks and also aims to investigate classroom attitudes to enhance students' language competence. These technologies enable the modification of teaching strategies through text analysis and image recognition, providing comprehensive feedback on student interactions. For this study, the Multimodal Emotion Lines Dataset (MELD) and eNTERFACE'05 datasets were selected. eNTERFACE contains 3D images of individuals, while MELD analyzes spoken patterns. To address over fitting issues, the SMOTE technique is used to balance the dataset through oversampling and under sampling. The study accurately predicts human emotions using Federated 3D-CNN technology, which excels in image processing by predicting personal information from various angles. Federated Learning with 3D-CNNs allows simultaneous implementation for multiple clients by leveraging both local and global weight changes. The NLP system identifies emotional language patterns in students, laying the foundation for this analysis. Although not all student feedback has been extensively studied in the literature, the Fed 3D-CNN and LSTM algorithm recommendations are valuable for extracting feedback-related information from audio and video. The proposed framework achieves a prediction accuracy of 97.72%, outperforming existing methods. This study aims to investigate classroom attitudes to enhance students' language competence.
