Abstract:

The report contains the results of an investigation using a digital Voice Data Processor AD-286 097, AD-286 158. The system is a special-purpose data processor designed to support research on digital voice communications and, in particular, the evaluation of a speech bandwidth compression technique. Although the continuing investigation has provided support to the research effort, it has more pertinently styled the growth of the data processor as a research tool. The most significant modification to the system has been the incorporation of two digital magnetic tape units as additional inputoutput equipments. Other changes which have been made include the capability of compiling rank-ordered data in tables of specified values for pattern frequency the tabulating the frequency distribution of pattern deviation values and, the tabulation of the number of missed pattern matches in a specific number of voice samples. These changes have significantly expanded the capability and flexibility of the processor and also greatly decreased the general processing time required. With the increase in capability has gone a comparable increase in programming requirements by the operator the revised System Operating Instructions are included as Appendix A. Author
