Speech Lock

Security - Safety Projects / Muhammad Bilal

we designed and implemented a speaker recognition device that acts as a lock triggered by the sound of your voice saying a specific passcode. The implementation uses hardware filtering from a microphone and many signal processing concepts in software. All software and matching is implemented in the ATmega1284p. The lock has two modes: training and

SingLock

Security - Safety Projects / Muhammad Bilal

SingLock is a pitch-based security system based on ATMEL MEGA1284P microcontroller featuring two password protection stages: one based on a 4-digit numeric personal identification number inputted via the keypad and another based on two pitches inputted via the microphone. Most security systems we find today are keypad and/or keyboard-based. Speech, rather than button-pressing and/or typing,
