Abstract

Methods, systems, and devices for abnormal sound detection are described. An audio recording of a mechanized environment may be obtained. First sounds extracted from the audio recording may be categorized into a set of categorical sounds. A library of first sound patterns may be generated using the categorical sound and based on second sounds extracted from the audio recording. The first sound patterns may include sequences of the categorical sounds. Audio data including audio signals capture by sensors in the mechanized environment may be received, and second sound patterns detected in the audio signals may be compared with the first sound patterns. Based on comparing the second sound patterns with the first sounds patterns, a sound pattern that is not in the library of the first sound patterns may be identified. An alarm may be generated based on detecting the sound pattern a threshold quantity of times.
