Abstract
A modified AMDF pitch detection algorithm is presented. The amplitude character of the basic AMDF of speech signal is modified by means of a simple linear transform in our algorithm. Then the pitch-point determining method, that taking the global minimum valley point of AMDF as the pitch period calculation point, can be employed in pitch detection, even for the voiced speech with good stability and periodicity. The simulated experiments indicate the performance is improved considerably relative to the conventional AMDF method.
