Abstract
Abstract An apparatus for use in an outboard engine provides a voice alarm output when an abnormality of cooling water or the like is detected during operation of a radio or the like, the abnormal state being announced with a synthesized voice. The apparatus has a plurality of sensors for detecting the abnormality of the cooling water and the like, and a voice output circuit to receive detection signals from the sensors and to output a synthesized voice signal identifying the abnormal state. An acoustic reproducing apparatus such as a radio is provided, and a common speaker is used to output the radio output or the voice output signal of the voice output circuit. A voice discriminating switching circuit is provided between the voice output circuit and the acoustic reproducing apparatus. The voice discriminating circuit detects the level of an output signal of the voice output circuit and temporarily switches the speaker from the acoustic reproducing apparatus to the voice output circuit in response to the level.
