In a navigation system, a switching use dictionary is provided as storing an aggregation of switching commands, which are also stored in the individual language-specific dictionaries including the language 1 dictionary, language 2 dictionary, . . . , and language n dictionary. It is determined whether a switching command included in the switching use dictionary is matched with an inputted speech. When a certain switching command is determined to be matched with the inputted speech, a certain language-specific dictionary corresponding to the certain switching command is substituted for a default active language-specific dictionary. Thus, the certain language-specific dictionary is newly selected as an active language-specific dictionary used for operating the navigation system by a speech input.
