“…Many different algorithms have been proposed to estimate the speech model parameters, such as using expectationmaximisation algorithm [4,5], subspace non-iterative algorithm based on orthogonal projection in [6], log-spectral amplitude minimum-mean-square-error (MMSE) in [7], power spectral subtraction method in [8,9], comparison to a masking threshold that computed from both time and frequency-domains simultaneous masking properties of human auditory systems in [10], estimation of the clean-speech short-term predictor parameters from noisy speech using maximum-a-posteriori and MMSE techniques in [11]. Besides, the use of the Kalman filter in the speech recognition system to improve the speech recognition accuracy has been proposed in [12,13], Mathe et al [14] have used the Kalman filter for speech enhancement purpose.…”

“…The presence of background noise in speech significantly reduces the intelligibility of speech. Degradation of speech severely affects a person's ability, whether impaired or normal hearing, to understand what the speaker is saying [7]. Recent researches have developed a variety of theoretical methods to fight this problem, but the complexity of this task is always linked to the random nature of the noise and the inherent complexities of speech.…”

“…This paper presents a method for speech enhancement based on a dynamic smart Gaussian filter. Our aims is to remove real-colored noise which have, unlike white Gaussian noise (WGN), a spectrum that is not flat [7]. Therefore, the noise does not affect the speech signal uniformly over the whole spectrum.…”
