Abstract. Secure structures are right now shielded from unapproved access by an assortment of gadgets. Despite the fact that there are numerous gadgets to ensure the system wellbeing, for example, PIN entry devices, electronic devices, cryptographic techniques and double control methodology and the individual’s voice are utilized. The ability to confirm the character of a speaker by investigating discourse, or speaker check, is an appealing and moderately subtle method for giving security to entrance into a significant or made sure about spot is questionable. The voice of a particular speaker cannot be taken, lost, overlooked, speculated, or imitated with precision. To alleviate the above limitations, this undertaking depicts structure and prototyping a voice-based intelligent door access security system for the buildings. In the proposed system, the entrance locking system is approved with the help of an enlisted client talking into a mouthpiece attached to the system. Moreover, intelligent system approach is utilized to create an approval process by verifying the individual models dependent on their voice. The proposed method is used to open and close the door using voice command. Voice command will be stored in an easy VR via mic for further processing. If the stored voice is detected door will be opened automatically. Any other voice will be detected that information and displayed in LCD.
