To develop a system to recognize system commands through voice and convert it into equivalent text, the system accepts voice commands from user and displays its equivalent text. The system accepts voice commands, performs processing on it to recognize the actual command before displaying the corresponding output. For this particular system processing being done are noise removal, feature extraction and pattern matching. Various features are available. These are totally application dependent i. e. for a particular application particular feature is being extracted. Hence performing this various processing, text format of equivalent voice command is being displayed. To accept the voice commands User Must use a good quality microphone. The voice commands is being recorded and saved as a . wav file. Wav file is being used because it stores the data in the digital form. Initially the features of each command would be saved in a file. Once the 'init' is recognized the system will then wait for the users commands. On getting a command the system will save the input as a . wav file. The features of this command are then matched against the predefined command features. If the match is found the command is a valid one. It then displays its text form. If the command is not valid it simply discards it.
