Development of Contactless Door Lock System Using Text-Dependent Voice Authentication

Electronic door locks offer advantages over traditional locks, but many require physical contact for password entry, raising virus transmission concerns. This study presents a voice recognition electronic door lock prototype, allowing users to unlock doors through smartphone voice commands, eliminating physical contact. Key findings include successful integration of voice recognition technology and the use of an Arduino Voice Control app as a user-friendly interface. Users can speak the door password, transmitted via Bluetooth to unlock the door securely. Rigorous testing affirms the prototype's functionality, assuring accurate voice recognition for door access. This innovative solution caters to modern security needs and addresses virus transmission concerns associated with traditional electronic locks.
