Speech intelligibility, clarity, and naturalness may all be improved by the use of signal processing techniques. You may come across similar processing in applications like mobile telephony, internet telephony, or the personal intercom. It is possible to increase speech quality or performance by using implementation-specific benefits via sophisticated domain selection for implementation (digital, analogue, and hybrid). Speech-enhancement applications in the three domains of implementation are the focus of this research. Using a simple but effective speech enhancement method, the advantages and disadvantages of each implementation will be shown
