| Summary: | In this paper, we propose a method for designing a classification model of speech emotional state based on the feature-map fusion of temporal convolutional network (TCN) and the pretrained convolutional neural networks (CNN) from Korean speech database. For this purpose, the proposed approach is comprised of four main stages. In the first stage, we extract Mel-frequency cepstral coefficient (MFCC) and gammatone cepstral coefficient features (GFCC) in the frequency domain as well as log-Mel spectrogram in the time-frequency domain. From these features, the second stage performs training process using TCN and the yet another audio Mobile Net network (YAMNet), respectively. In the third stage, we perform feature-map fusion using canonical correlation analysis (CCA), stationary wavelet transform (SWT), and fuzzy c-means-based principal component averaging (FCMPCA), respectively. From these steps, speech emotion recognition model is effectively designed through the fusion model of TCN and YAMNet as well as feature-map fusion methods. Finally, we evaluate the performance comparison from five databases: the AI-Hub speech emotion dataset built in Korea and Korean speech emotional state classification dataset built from Chosun University as well as Emo-DB, RAVDESS, and TESS datasets. The experimental results showed that the proposed model revealed good performance in comparison to other previous works in most datasets. |
