PROBLEM TO BE SOLVED: To eliminate the possibility that speeches not intended by a user are inputted by attaining the state of not accepting speech input exclusive of a specific command speech when the user interrupts utterance for a specified period of time. SOLUTION: The speech introduced from an input section 11 is subjected to recognition processing and are converted to character strings in a speech recognition section 14. These character string are processed through a command forming section 15 or text forming section 17. At this time, the input intervals of the speech are monitored in a speech input judgment section 17. If the speeches are not inputted even after the specified time, a speech input mode is turned off to make the character strings inputted during this time ineffective. As a result, the possibility that the unnecessary speeches, such as external sounds and the speeches not intended by the user, are inputted while the user interrupts the speech input is eliminated. |
