一、引言由于集成电路价钱低,体积小,有可能设计出专用计算机,以便从输入到基音激励信道声码器的语言中提取基音信息。(此声码器是林肯实验终端的一部分。)基音计算机设计是基于 B.Gold 发明的计算法,仅做小的改动,以利于硬部件的实现。Gold 最初写的文章——收入附录中——相当详细地叙述了基音提取算法。
I. INTRODUCTION Since integrated circuits are inexpensive and small in size, it is possible to design a special purpose computer to extract pitch information from the language input to the pitch-driven vocoder. (The vocoder is part of the Lincoln Experimental Terminal.) The pitch computer design is based on the algorithm invented by B. Gold, with only minor changes to facilitate hard component implementation. Gold’s original article, Income Addendum, describes the pitch extraction algorithm in great detail.
