| Abstract: | A pitch detection algorithm based on auto-correlation function(ACF) was proposed and improvement can be achieved by the use of the modified ACF.According to ACF in combination with pre-processing and post-processing technique,the discrimination on sonant and surd excitation speech signal and pitch detection of sonant excitation speech signal can be completed effectively. |
