Pitch detection and estimation is a very important problem in speech signal processing. Now some scholar has presented a simple and effective method in pitch detection. It lessens the computing burden, but still has some defects for practical application. Here we improve this simple algorithm effectively, and introduce a method based on positive-negative area into it for pitch detection. Its good performance has been shown in text-to-speech system and speaker recognition.
