Very little research on Tibetan speech pitch detection has been published. Tibetan speech pitch detection is im?portant part of Tibetan speech processing,whose accuracy affects system performance directly. The center clip algorithm,algo?rithm principle of autocorrelation function and pitch detection algorithm are introduced. The procedure of Tibetan speech pitch detection was designed. The programming and simulation are executed with Matlab software. The result shows that the algorithm has simple structure,accurate result and small amount of calculation. It can be applied to detecting Tibetan speech pitch period in low SNR environment.
