The device utilizes voice recognition technology connected to a hydraulic locking system. By incorporating a microphone and sound module, this device can recognize and respond to voice commands, allowing users to open the door without the need for a physical key. The aim of developing this device is to enhance convenience and security in accessing doors, enabling users to rely solely on their voice. Additionally, the device is equipped with an emergency button that allows for manual door opening in case of technical issues or emergency situations. This innovation is expected to provide a practical and efficient solution for door locking systems. The method used involves research and development based on previous studies. The results of this device have successfully been created in the form of a prototype.
