Abstract: A system and a method for detecting anomalous sound are disclosed. The method includes receiving an audio signal from a sound source in a recording environment. The sound source and the recording environment are characterized by a set of attributes including a first attribute pertaining to a first attribute type and a second attribute pertaining to a second attribute type. A multi-head neural network is trained to extract from the received audio signal a first embedding vector indicative of the first attribute type and a second embedding vector indicative of the second attribute type. The first embedding vector is compared with a first set of embedding vectors to classify attributes of the first attribute type and the second embedding vector is compared with a second set of embedding vectors to classify attributes of the second attribute type, to determine a result of anomaly detection.

Abstract: Embodiments of the present disclosure disclose a system and method for extraction of a target sound signal. The system collects collect a mixture of sound signals. The system selects a query identifying the target sound signal to be extracted from the mixture of sound signals, the query comprising one or more identifiers. Each identifier is present in a predetermined set of one or more identifiers and defines at least one of mutually inclusive and mutually exclusive characteristics of the mixture of sound signals. The system determined one or more logical operators connecting the extracted one or more identifiers. The system transforms the one or more identifiers and the extracted logical operators into a digital representation. The system executes a neural network trained to extract the target sound signal by mixing the digital representation with intermediate outputs of intermediate layers of the neural network.
