Abstract: This paper describe Computer control with voice command using soft computing tool Matlab. The system enlightens upon the invention as well as technological advancement in the field of voice controlled computer using Matlab. In this paper the concept of voice recognition is use to control the computer. Initially analog voice input will be given to computer using microphone which will be recorded in samples and the MFCC feature is extracted from that voice command and it is stored in the database. The real time input voice command to be executed will be send to the computer that will be compared with stored data base by MFCC algorithm and if the match is found then particular operation is performed. This system will be helpful for physically disabled persons and also for the peoples who needs simple access to their computer.

Keywords: Command Execution, Database Generation, Feature Extraction, Speech Recognition, MFCC.
