Abstract
The invention relates to a method for airborne-sound acoustic monitoring of an exterior and/or an interior of a vehicle, in which at least one microphone (1) is used to convert airborne sound into an electrical signal (S) and to route it for evaluation purposes to a device for voice and/or sound recognition (2). According to the invention, the electrical signal (S) is subjected to a pre-evaluation in a device for trigger detection (3), and detection of a trigger results in the device for voice and/or sound recognition (2) being moved from an inactive or partially active state to a fully active state by means of the device for trigger detection (3). Further, the invention relates to an apparatus for airborne-sound acoustic monitoring of an exterior and/or an interior of a vehicle and to a vehicle having such an apparatus. The subject matter of the invention is also a computer-readable storage medium.
