8. MODULES Voice Tracking Module This entire module is implemented in a thread where it continuously listens to the voice by switching on and off the microphone. This module will be provided with the user interface to record a voice. Voice Analysis and Storage Module This modules uses the phonetic decoding using phoneme approach. This module will analyze the voice and extracts words or sentences from the voice tags. This module is responsible for converting the listened data into English words by the process called phonetic decoding. Authentication Module Admin Module This module is responsible for the comparison of present voice tag with the existing voice tags in the systems. It will take the support of the voice tracking module and the voice analysis module to compare the voices and read the microphone. This module is used by the administrator of the security system. It is responsible for registration of users, deleting the existing user. By passing the security for the specific users … etc., This module will take help from the voice tracking module for registration of new users.
