ABSTRACT:
A recognition result determination section determines whether or not a character string identified by a speech recognition section through a speech recognition process includes a desire type character string (non-specific instruction type operation character string) in which an object to be operated is not specified. Further, a request level determination section determines a request level related to the desire type character string by detecting a change in sound pressure level on the basis of a speech signal. When the recognition result determination section makes a positive decision, a level-based instruction execution section specifies the object to be operated and gives a predetermined operation instruction on the basis of a content of the desire type character string and a request level determination result.
