低比特率的高质量语音（例如，2400 bits/s）是当前语音研究的重要目标之一。作为这个问题的长期活动的一部分，我们已经开发出一个有效的计算机程序，将作为一个工具，用于调查是否发音语音合成可以实现这种低比特率。在8 kHz的采样频率下，包括鼻音和摩擦音在内的最全面的程序版本在Cray-1计算机上以大约两倍的真实的时间运行。
High quality speech at low bit rates (e.g., 2400 bits/s) is one of the important objectives of current speech research. As part of long range activity on this problem, we have developed an efficient computer program that will serve as a tool for investigating whether articulatory speech synthesis may achieve this low bit rate. At a sampling frequency of 8 kHz, the most comprehensive version of the program, including nasality and frication, runs at about twice real time on a Cray-1 computer.
