    摘要: A method and apparatus for robust speaker localization and a camera control system employing the same are provided. The apparatus for speaker localization includes: a difference spectrum obtaining section which obtains a difference spectrum of a first pseudo-power spectrum for a speech section and a second pseudo-power spectrum for a non-speech section detected in a voice signal output from a microphone array; and a speaker direction estimation section which detects a peak value in any one of the difference spectrum and the first pseudo-power spectrum, and estimates the direction of a speaker based on the direction angle corresponding to the detected peak value.
