New lightweight model enhances speech emotion recognition with explainability

Researchers have developed a new framework for speech emotion recognition (SER) that prioritizes both accuracy and transparency. This lightweight deep learning model uses compact convolutional neural networks and log-Mel spectrograms to analyze speech characteristics. To enhance interpretability, the system incorporates Grad-CAM to visualize which parts of the audio signal influence its predictions. Evaluations on the SAVEE dataset show the model achieves competitive performance with fewer parameters than existing SER models, offering a practical balance between accuracy, efficiency, and transparency.
