The method adds to the existing pitch detection method the steps of: detecting a highly autocorrelated region (upper 45% of a speech signal peak distribution) to accept it as the candidate region for the pitch detection; padding the excluded region by zeros; applying the pitch detection algorithm only to the candidate region, thereby reduces the pitch detection time.
