In recent years, however, attempts have been made to alert and inform the contents of this abnormal state by the sound of the sound monitor device.

For example, in Japanese Patent Laid-Open No. 61-25417, a message signal that does not require an emergency based on a predetermined sensor among a plurality of message signals is to be held in a stopped state based on the operation of an alarm stop means and repeatedly output. There is disclosed a voice device for agricultural machinery, which is a means for repeatedly outputting a message signal that is stopped and an emergency is required until the signal from the sensor is changed, regardless of the operation of the alarm stopping means. As a result, messages that can be afforded without immediately causing serious problems will be
It is possible to prevent the message from being repeatedly uttered from the speaker by maintaining the stopped state by the operation of the alarm stop means,
The operator can continue the work without being bothered by the noise caused by the message, and the work efficiency can be improved. In addition, an urgent message that will cause serious trouble if it is not canceled immediately is repeatedly uttered to alert the operator even during the operation of the emergency stop means, and prevent serious trouble from being uttered. You can do it. Further, it is disclosed that an alarm by a horn and an alarm by a speaker based on voice can be switched by a changeover switch.

Further, Japanese Patent Laid-Open No. 58-174963 discloses a controller for forming guide information indicating the operating procedure of a copying machine according to the humidity condition,
An abnormal copy preventing apparatus is disclosed, which comprises an annunciator using a voice synthesizing means for guiding an operator of an operation procedure of a copying machine based on the guidance information. As a result, when the humidity of the paper storage unit is normal, the operator is informed that "copying is possible". Also, when it is determined that the humidity of the paper storage is too low, the controller sends this information to the alarm, and the alarm says "The humidifier is currently operating due to low humidity. Please wait for a while." Warning guidance to the operator. This is intended to prevent the occurrence of abnormal copying.

Further, in Japanese Patent Laid-Open No. 58-63537, a diagnosis is made by turning on a diagnostic switch, and if no abnormality is found, it is displayed as normal and voice also indicates that abnormality is found. In some cases, there is disclosed a centralized diagnosis system which sequentially displays the abnormality diagnosis information and informs it by voice. As a result, the diagnosis result is combined with voice notification, which is easy for the diagnostician to understand.
