In this paper, the authors introduce an intelligent evaluation method based on improved PSO-WNN (Particle Swarm Optimization-Wavelet Neural Network) for speech denoising in high background noise. Firstly, by using Lyapunov stability theory, convergence conditions of a single particle is discussed and based on the result, a new strategy is introduced to improve the performance of the PSO algorithm. Then, the improved PSO algorithm is used to optimize the parameter of the WNN and the LPSO-WNN is introduced.
