An algorithm is presented to determine the pitch of a signal in a very noisy environment adaptively and reliably. This algorithm is adaptive to input signal from frame to frame on both the correlative criterion and the energy criterion. The correlative criterion assumes that the input signal has a slowly time-varying property on adjacent frames. The energy criterion assumes that the input signal has some nonsignal frames to compute the statistics of noise energy. This algorithm has been useful in speech processing and speech coding. Implementation of this algorithm is simple and straightforward.>
