A speech recognition device controller is provided, which is capable of properly determining a user's leaning level in speech so as to provide an efficient interaction. It includes a voice input unit 2 for receiving speech input from a user, a speech recognition unit 3 for recognizing the input speech, a response output unit 10 for outputting a response to the user, and a device control unit 11 for controlling a device based on a recognition result of the speech recognition unit 3. It further includes an input item count detection unit 4 for detecting the number of items identified from the recognized speech among a given number of items necessary to control the device, a reference input item count setting unit 6 for setting a reference value for the number of items identified from the speech, an input item count comparison unit 7 for comparing the number of items detected by the input item count detection unit 4 with the reference value set by the reference input item count setting unit 6, a skill level determination unit 8 for determining the user's skill level in speech based on a comparison result, and a response control unit 9 for controlling the response output according to the determined skill level, wherein the user is prompted to enter a complete one-time speech input or a one-by-one series of discrete speech inputs, based upon the determined skill level.
