摘要：

Speech compression is a widely scoped field with multiple possibilities in the fields of digital communication and transmission of data. It is of particular importance in digital signal processing. There are many commercially available methods both in time and frequency domains to aid the same. Speech file has multiple frequent redundancies present in the raw data. Taking into account the possibility that the frequencies present can be effectively encoded without appreciable change in speech quality, this paper goes on to describe an efficient and new approach with a satisfactory compression ratio and PSNR value for a sampling rate.
