Speak Pass

The handy Speak Pass security system uses a speaker recognition algorithm to identify users. The voice signal is acquired through a microphone and sampled before the zero crossing rate is calculated and compared with each user password. After a user speaks into the LM3S811-based system, the LED displays a user identification or denied access message.
