Abstract: Because of nature of job, unhealthy social habits and voice abuse, people are subjected to risk
of voice problems It is well known that most of speech disorders causes changes in the acoustic voice signals
[9].In the recent year the trend towards automated analysis of pathological noise signal has gain momentum.
The awkwardness of analog equipment has simulated development of digital computer techniques for processing
and analysis of pathological speech signal in patient care system. The above filter design techniques &
prepossessing of speech signal can be used in any speech processing application.In this paper voices of patients
are taken and they are preprocessed. In prepossessing Speech signal is passed through Moving Average (M.A)
filter, High pass (H.P) filter for removal of noise & then framing and windowing is done. This preprocessed
output can be used for pathological voice recognition, speech identification, speaker identification & many
more application.
Keywords -Framing, High-Pass Filter, Moving Average Filter, Pathological Speech Signal,Windowing.
