Fatigue is a natural phenomenon which is a kind of self-regulation and protection for human body. Detection fatigue states have positive significance for all occupations now. This paper presents a feature-based parameters and the probabilistic neural network (PNN) speech recognition model to detect fatigue. Through training at different times of voice samples as the voice sources and establishing...
A robust speech feature extraction method based on the power law of hearing and non-uniform spectral compression technique is proposed, and the correspondent model compensation algorithm is given. The mismatch functions, reflecting the infections of additive noise and spectral compression, and the model compensation formulae are deduced. The experiment results show that the significant improvement...
