Abnormal sound detection in a mechanized environment

An apparatus, comprising:

• one or more processors;
• and
• memory storing instructions that are executable by the one or more processors to cause the apparatus to:
• obtain an audio recording of a mechanized environment:
• categorize first sounds extracted from the audio recording into a set of categorical sounds;
• generate, using the set of categorical sounds, a library of first sound patterns based on second sounds that are extracted from the audio recording, the first sound patterns comprising sequences of categorical sounds of the set of categorical sounds;
• receive audio data comprising audio signals captured by one or more sensors in the mechanized environment:
• compare, based on receiving the audio data, second sound patterns detected in the audio signals with the first sound patterns;
• and
• identify, based on comparing the second sound patterns with the first sound patterns, a sound pattern of the second sound patterns that is excluded from the library of the first sound patterns.

A non-transitory, computer-readable medium that stores code that comprises instructions executable by a processor of an electronic device to cause the electronic device to:

• obtain an audio recording of a mechanized environment:
• categorize first sounds extracted from the audio recording into a set of categorical sounds;
• generate, using the set of categorical sounds, a library of first sound patterns based on second sounds that are extracted from the audio recording, the first sound patterns comprising sequences of categorical sounds of the set of categorical sounds:
• receive audio data comprising audio signals captured by one or more sensors in the mechanized environment;
• compare, based on receiving the audio data, second sound patterns detected in the audio signals with the first sound patterns;
• and
• identify, based on comparing the second sound patterns with the first sound patterns, a sound pattern of the second sound patterns that is excluded from the library of the first sound patterns.
