We created a smart voice decoder system that is capable of recognizing vowels in human speech. The audio input is sampled through a microphoneamplifier circuit and analyzed in real time using the Mega644 MCU. The user can record and analyze hisher speech using both hardware buttons and custom commands through PuTTY. In addition, the final product also supports a simple voice password system where the user can set a sequence of vowels as password to protect a message via PuTTY. The message can be decoded by repeating the same sequence via the microphone.
