Abstract: Disclosed are a method and system for positioning a sound source by a robot. With a combination of delay estimation and power spectrum intensity, the approximate direction of the sound source is estimated according to the power spectrum intensities received by the sound source acquisition apparatuses and the spatial directions of the sound source acquisition apparatuses. As such, the approximate direction of the sound source may be accurately estimated. The power spectrum intensity comparison refers to calculating an average power spectrum intensity of the sound source acquisition apparatuses within a specific frequency interval, and the average power spectrum intensity is inversely proportion to the distance from the sound source to the sound source acquisition apparatuses.
