PURPOSE:To execute easily a self-diagnosis of a complicated circuit by providing a memory circuit for storing a known data. CONSTITUTION:A voice input is amplified, and thereafter, is inputted to an analog-digital converting circuit 2, is selected by a selecting circuit 4, and thereafter, is inputted to a self-correlation operating circuit 5. A self-correlation value is operated by this circuit 5, its result is stored in a temporary store memory 6, also its operation is executed by an operating circuit 7, and a voice is recognized by a discriminating CPU9. A storing circuit 3 provided newly for storing a known input data is connected to the selecting circuit 4, it is selected when the diagnosis is required, a result of the operation of the self-correlation operating circuit 5 is read through a bus 8 by the discriminating CPU9, and whether its operation is executed correctly or not is self-diagnosed. |
