Abstract
In addition to the steady background noise, there are many non-stationary harmonic noises in the speech under the influence of fan noise, which has the characteristics of mutation and randomness.None of the existing speech enhancement algorithms can suppress the noise very well. In order to remove the non-stationary harmonic noise in the environment, improve the signal to noise ratio, and reduce the distortion of the speech after denoising, this paper proposes a new speech enhancement algorithm:1.A new threshold decision method is designed to achieve the effect of de harmonic. 2. Eliminating sudden noise of environment by noise estimation method. Experiments show that this algorithm not only improves the noise suppression ability in the non-speech zone, but also the denoising effect is better than traditional speech enhancement algorithm.

Speech enhancement based on soft audible noise masking and noise power estimation
This paper presents a perceptual model based speech enhancement algorithm. The proposed algorithm measures the amount of the audible noise in the input noisy speech based on estimation of short-time spectral power of noise signal, and masking threshold ...
Wavelet-Based Speech Enhancement Using Time-Adapted Noise Estimation
Spectral subtraction is commonly used for speech enhancement in a single channel system because of the simplicity of its implementation. However, this algorithm introduces perceptually musical noise while suppressing the background noise. We propose a ...
