<p><P>PROBLEM TO BE SOLVED: To ensure that speech recognition is performed without being accompanied by operation of a forward trigger. <P>SOLUTION: The system includes a speech/non-speech discrimination section 5 which discriminates whether the sound inputted from a speech input section 3 is speech or non-speech, a keyword dictionary 10, a dictionary 13 for speech recognition, a speech recognition section 8 which performs speech recognition based on the dictionary 13 for speech recognition, a speech keyword detection section 11 which detects whether the sound judged to be the speech in the speech/non-speech discrimination section 5 is a word previously registered in the keyword dictionary 10 or not, and a recognition instruction section 9 which emits the instruction to perform the speech recognition of the sound inputted at the time the sound inputted from the speech input section 3 is detected to be the sound including a word registered in the keyword dictionary 10 to the speech recognition section 8. The speech recognition is performed using the specific utterance after the user utters a desired word as a trigger. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
