Audio Anomaly Detection in a Speech Signal

Abstract:

Systems and methods for audio anomaly detection in a voice signal are provided. In some embodiments, a system comprises a voice history database storing historic audio metadata of past voice signals acquired during operation of a user audio device; a data clustering processor, connected to the voice history database and configured for cluster analysis of the historic audio metadata into a normal operation cluster and an anomalous operation cluster and to provide a user audio model therefrom; a voice model database, configured to receive and to store the user audio model; and a classification processor, connected with the voice model database. The classification processor may receive current audio metadata of the voice signal from the user audio device; compare the current audio metadata with the user audio model; and determine if the voice signal corresponds to a normal operating mode or an anomalous operating mode of the user audio device.
