Home security is extremely important, and several methods of security have been improved, such as the usage of alarms, monitoring systems, and the interplay of electronic hardware, software, and other factors. Keys can be misplaced and found by others, putting the guarded structure at risk; keys can also be fabricated or stolen. This project entails creating a voice message-based door access system that can both open the door and identify intruders, trespassers, criminals, or any other type of illegal behaviour. The speech-controlled door was meant to generate a voice message based on the input data and was developed around a microcontroller (ATmega328p). A speech recognition module is used to allow the owner or user entry to the door. To gain access to the door, the owner must first utter the specific speech or key word required to open it. A voice notification is then outputted through the associated speaker if the pronounced word does not match the speech recognized by the microcontroller. To signify that access is refused, a red-light emitting diode will flash. The microprocessor would activate a relay and current will flow through the latch, allowing the door to be unlocked, if the uttered speech matches.
