US 2022/0044698 A1 · ACOUSTIC EVENT DETECTION SYSTEM AND METHOD

Abstract

An acoustic event detection system and a method are provided. The system includes a voice activity detection subsystem, a database, and an acoustic event detection subsystem. The voice activity detection subsystem includes a voice receiving module, a feature extraction module, and a first determination module. The voice receiving module receives an original sound signal, the feature extraction module extracts a plurality of features from the original sound signal, and the first determination module executes a first classification process to determine whether or not the plurality of features match to a start-up voice. The acoustic event detection subsystem includes a second determination module and a function response module. The second determination module executes a second classification process to determine whether the features match to at least one of a plurality of predetermined voices. The function response module executes one of functions corresponding to the predetermined voices that is matched.
