| Abstract: | A normalized cross correlation function pitch detection algorithm (NCCFPDA) is proposed in this paper. The efficient pre processing and post processing technologies are introduced before and after the main pitch determination processes. The experimental analysis show the performance is very satisfactory for pitch extraction and unvoiced/voiced decision with this method under the general background noise. |
