What's Happening?
A new study has developed a deep learning framework for gender-sensitive speech emotion recognition using MFCC feature selection and SHAP analysis. The framework utilizes a probabilistic neural network and a Gaussian Mixture Model to classify emotions such as anxiety, delight, and wrath. The study found that classification accuracy varied by gender, with females achieving higher accuracy rates than males. The proposed model outperformed existing architectures like VGGNet and ResNet-50, achieving an overall accuracy of 89.5%. The framework demonstrated faster training convergence and lower computational overhead, making it suitable for real-time applications.
