hello there
i am designing a module for car security system. basically few selected people voices will be pre recorded in a system where the individuals will say e.g ENGINE START and the module compare their voice with the pre recorded voice. If their voice is same as that of already saved. The module will initiate engine ignition.
i have just made a general layout for my system. where speaker will pass the message to HM2007. the IC will compare the voice with saved message and a micro controller will ignite the engine.
i am looking for the suggestion in this regard or some modification that will help in reliability and compact size of module for car.
Thanks in Advance.
