From the project
A voice-activated AC outlet
This circuit allows the user to turn an AC outlet on or off using a simple (or not so simple!) phrase, such as "Aziz, light!!". Note that it is not an intelligent circuit in that it does not repsond to specific commands, but only to the amplitude of the detected speech.
It does, however, provide the illusion of intelligence, as well as mitigations against false positive responses that typically plague such simple voice-activated circuits.
