Speech Fatigue Detection Based on Deep Learning

Abstract

Medically speaking, moderate fatigue is the embodiment of workload, and excessive fatigue will cause adverse effects on the human body. Therefore, real-time monitoring of human fatigue is of great significance. In order to detect fatigue in real time and conveniently, a speech fatigue detection method based on deep learning is proposed in this paper. The main work of this paper is to screen the useful speech segments of the fatigue corpus created in the previous work; Secondly, the speech signal is preprocessed and the analog speech signal is digitized; Thirdly, deep learning can effectively reflect the phonetic features of fatigue information; Finally, the fatigue degree is classified and recognized by classifier. The best classification and recognition rate of speech fatigue detection based on BLSTM network recommended by the author can reach 92.7%, which realizes the effective recognition of sports fatigue.
