Study on Speech Synthesis by Sparse Modelling in Noisy Environment: A Review

Abstract: The estimation of unseen noise is the major challenge in speech enhancement algorithm in adverse environments. It is difficult to understand the speech signal under presence of noise from background areas. The human speech and hearing system is inherently sensitive to interfering noise. The use of speech enhancement algorithm removes or reduces the presence of noise. The aim of the noise reduction algorithms is to estimate the clean speech signal from the noisy recordings in order to improve the quality and intelligibility of the enhanced signal. Due to this, it presents a review on method for speech enhancement using mask estimation iteratively. In this work, it will provide the concept of optimization of cost function by iterative method. This will help for reducing the noise from signal. All simulations will be implemented in MATLAB.
