In this paper, we review speech enhancement techniques. Speech enhancement is
necessary for many applications in which clean speech signal is important for further …

This paper reviews the past and the recent research based on adaptive noise cancellation
system using Adaptive filter algorithms. Adaptive noise cancellation is a wide area of …

The quality and intelligibility of the speech are usually impaired by the interference of
background noise when using internet voice calls. To solve this problem in the context of …

Speech enhancement is used in almost all the modern communication systems. It is obvious
that when speech is being transmitted, its quality may degrade due to interference in the …

Environmental noise can pose a threat to the stable operation of current speech recognition
systems. It is therefore essential to develop a front feature set that is able to identify speech …

In this paper Adaptive Wiener filter is used for enhancement of the speech signal which is
corrupted by additive noise. Adaptive Wiener filter uses NLMS algorithm for cancelling noise …

Seismic stations and seismic arrays suffer from unwanted seismic noise as a result of
inevitable population growth and development. This encroachment of noise degrades …

Flexibility and programmability of hearing aids are important because the algorithms applied
to hearing aids should be changeable based on different types of hearing impairment and …

In order to improve the intelligibility and quality of speech signal under different noise
environments, an improved multi-band spectral subtraction algorithm using Mel-scale is …

Flight operations, being conducted both in commercial and military sectors, demand reliable
and real-time radio communication between the aircraft and air traffic controlling (ATC) …
