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.
