Abstract
An equalizer apparatus comprises a sampled voice data extractor, a sampled noise data extractor and a sampled voice data characteristics corrector. The sampled voice data extractor extracts sampled voice data in a first time slot from the sampled voice data corresponding to a received voice signal. The sampled noise data extractor extracts sampled noise data in the first time slot and a second and third time slots before and after the first time slot from the sampled noise data corresponding to noise in a surrounding area of the apparatus. The sampled voice data characteristics corrector corrects characteristics of the sampled voice data in the first time slot extracted by the sampled voice data extractor based on characteristics of the sampled noise data in the first through third time slots extracted by the sampled noise data extractor.
