摘要：
The present invention relates to a method and apparatus for pitch search. One method includes: obtaining a characteristic function value of a residual signal, where the residual signal is a result of removing a Long-Term Prediction (LTP) contribution signal from input speech signals; and obtaining a pitch according to the characteristic function value of the residual signal.
