1. A localization system for identifying a position of a sound source using propagation times of a sound wave propagating from the sound source to a plurality of microphones, comprising:

  • an object detection unit which detects a position, a shape, and the like of a surrounding object present around the plurality of microphones; and

    a sound source position estimation unit which estimates a position of the sound source based on the propagation times, whereinthe sound source position estimation unit has a reflection wave path estimation function for estimating a reflection wave path and its distance from the surrounding object identified by information from the object detection unit, and based on the reflection wave path and the distance, the sound source position estimation unit estimates the position of the sound source.
