Sound warning system

Abstract

Abstract PURPOSE:To improve the certainty of warning transmission by recognizing a sound inputted with being partitioned by plural times in a determined time after being off-hooked and outputting warning in a place to be shown when a specified word is regularily coupled. CONSTITUTION:When a hand set 2 is off-hooked, such a condition is detected by a control part 6 and a gate signal is generated over a prescribed time from an off-hook time. An analog switch 7 is switched and controlled by this gate signal and a sound signal is inputted from the hand set 2 to a sound recognizing part 5. Word sound recognition is executed to the sound signal by the recognizing part 5. A coupling deciding part 6a of the control part 6 decides whether the recognized result of the sound is the coupling of the specified words determined in advance or not. When it is confirmed that the recognized result is the regular coupling of the specified words determined in advance, the warning is outputted to a warning device 8 in an announcing destination to be shown by the coupling.
