Emotion Speech Recognition Based on Adaptive Fractional Deep Belief Network and Reinforcement Learning

摘要

The identification of emotion is a challenging task due to the rapid development of human-computer interaction framework. Speech Emotion Recognition (SER) can be characterized as the extraction of the emotional condition of the narrator from their spoken utterances. The detection of emotion is troublesome to the computer since it differs according to the speaker. To solve this setback, the system is implemented based on Adaptive Fractional Deep Belief Network (AFDBN) and Reinforcement Learning (RL). Pitch chroma, spectral flux, tonal power ratio and MFCC features are extracted from the speech signal to achieve the desired task. The extracted feature is then given into the classification task. Finally, the performance is analyzed by the evaluation metrics which is compared with the existing systems.
