摘　　要：本文研究了语音压缩编码中基音预测器的两种情形,即开环和闭环结构。提出了一些简化基音预测器求解方法,比较了几种条件下的基音预测器性能。给出了计算机仿真结果。This paper studies two kinds of methods for pitch predictor in speech compressing coding, i. e., open-loop and closed-loop structure. Some of simplified approachs for solving pitch predictor equation are suggested, and the performances are compared under several conditions. The computer simulation results are shown.
