SOUND SOURCE DETECTION SYSTEM

摘要

A sound source detection system for detecting a sound source (e.g., running sound of a vehicle) based on sound collected by microphones extracts characteristic amounts from the sound collected by the microphones, sets a plurality of classes according to the position of the sound source by a multi-class pattern recognition method (e.g., multi-class SVM) using the characteristic amounts, extracts characteristic amounts from sound collected by the microphones for detection of a sound source, determines a class to which the extracted characteristic amounts belong, from the preset plurality of classes, and estimates the sound source based on the class.

主权项

1. A sound source detection system for detecting a sound source based on sound collected by a sound collecting device, comprising:
a classifying unit configured to extract a plurality of characteristic amounts from the sound collected by the sound collecting device, and to set a plurality of classes according to a position of the sound source by a multi-class pattern recognition method, using the characteristic amounts; a class determining unit configured to extract the characteristic amounts from the sound collected by the sound collecting device when detecting the sound source, and to determine a class to which the extracted characteristic amounts belong, from the plurality of classes set by the classifying unit; and a sound source estimating unit configured to estimate the sound source, based on the class determined by the class determining unit.
