In many speech communication systems, the presence of the background interference causes the quality or intelligibility degraded. Noisy environment also reduces listener?s ability to understand what is said. In addition to interpersonal communication, speech can also be transmitted across telephone channels, loudspeakers or headphones. The Quality of speech can also be influenced in data conversion, transmission or reproduction replica audemars piguet. The goal of speech enhancement method is to reduce background noise, or suppress channel interface or speaker interface to improve the quality of the speech. The goal of our work is to improve overall speech quality by increasing the intelligibility and reducing background noise. We used a band pass filter to filter out the unwanted noise which is followed by a post spectral subtraction filter. The performance is checked using signal to noise ratio.
