This project concerns the study of both forward and backward adaptive speech coding structures that operate at 6.4 to 16 kilobits per second. Techniques involved are integer and fractional rate trees, unweighted and weighted squared error distortion measures, the (M,L) tree search algorithm, and incremental path map symbol release. Speech compression to these rates has a number of important applications, including speech storage, voice mail, military communications, commercial telephony, and land mobile radio.

该项目涉及以每秒 6.4 至 16 kbit 的速度运行的前向和后向自适应语音编码结构的研究。涉及的技术包括整数和分数速率树、未加权和加权平方误差失真测量、(M,L)树搜索算法以及增量路径映射符号释放。这些速率的语音压缩具有许多重要的应用，包括语音存储、语音邮件、军事通信、商业电话和陆地移动无线电。
