1. A voice recognition device controller comprising: a voice input unit configured to receive a one-time speech input from a user containing a plurality of items necessary to control a device, wherein the items in the input user's speech necessary to control the device include at least (1) an application of the device, (2) an operational object of the application, (3) an operational content of the operational object, and (4) at least one operational parameter of the operational content: a voice recognition unit configured to recognize the plurality of items necessary to control the device from the one-time speech input to the voice input; an input item count detection unit configured to count the total number of items necessary to control the device recognized in the current input one-time speech of the user by the voice recognition unit a reference input item count setting unit configured to set a reference value for the number of items identified from the current input one-time speech of the user based on a driving load on the user, wherein the reference value for the number of items is higher or lower than the actual number of items identified by the input item count detection unit; an input item count comparison unit configured to compare the total number of items detected by the input item count detection unit from the current input one-time speech with the reference value for the number of items set by the reference input item count setting unit; a learning level determination unit configured to determine a learning level in speech of the user based on a comparison result of the input item count comparison unit; a response control unit configured to control the response output from a response output unit according to the learning level determined by the learning level determination unit, wherein, if the determined learning level in speech of the user is high, the response output prompts the user to input at one-time a plurality of items necessary to control the device, and if the determined learning level in speech is low, the response output prompts the user to input items necessary to control the device one by one; and a device control unit configured to control the device based on the user input.
