Speech Emotion Recognition Using Deep CNN-BiLSTM with Attention Mechanism on EMO-DB Dataset

Role: First AuthorDecember 2025 (Accepted)Guide: Dr. Anjali T, Amrita Vishwa Vidyapeetham

Proposed a deep learning architecture combining CNN and BiLSTM with attention mechanism for robust speech emotion recognition.

Achieved 98.13% accuracy on EMO-DB dataset across seven emotion classes, demonstrating effective feature extraction and temporal dependency modeling.

Designed and trained the architecture in PyTorch; performed comparative evaluation and ablation studies to validate model robustness against baseline approaches.
