in speech recognition functionality for recognizing responses spoken into microphone 66 audio signals received through microphone 66 are converted to electrical signals and sent to a preamp and gain control circuit 68 circuit 68 is controlled by an automatic gain control circuit 70 which is in turn controlled by microcontroller 56 after being amplified by preamp 68 the electrical signals enter chip 54 and pass through a multiplexer 72 and an analog to digital converter adc 74 the resulting digital signals pass through a digital logic circuit 76 and enter microcontroller 56 for speech recognition audio processor chip 54 also includes a ram 80 for short term memory storage and a rom 82 which stores audio sounds for speech synthesis and programs executed by microcontroller 56 to perform speech recognition and speech synthesis chip 54 operates at a clock speed determined by a crystal 84 chip 54 further includes a clock 78 which provides the current date and time to microcontroller 56 microcontroller 56 is also connected to control buttons 50 and 52 to receive user input toy 26 is preferably powered by one or more batteries not shown alternatively the toy may be powered by a standard wall outlet both methods for supplying power to a toy are well known in the art the toy 26 further comprises a motion system 79 that receives control signals from the microcontroller 56 the motion system 79 can be similar to the motion system used in the u201c furby u201d doll this system 79 allows the toy 26 to shake move its hands and feet and open and close its mouth and eyes the motion system 79 is well known in the art but is conventionally preprogrammed at the factory for particular ranges and sequences of movement referring again to.
