%X According to the mechanism of speech signal, an effective pitch detection algorithm by combined liner predictive coding with maximum likelihood was proposed. The algorithm adopts frequency partition to estimate the range of pitch period, improving the computational speed. Simulation experiments show that the pitch extracting results of the algorithm are superior to that of the conventional algorithms, overcoming the random errors and multiple or half frequency errors, especially robust at low SNR.
