Abstract:

The report contains the results of an investigation of speech pattern-matching using a digital voice data processor to evaluate pattern-matching speech bandwidth compression techniques. The capability and flexibility of the Voice Data Processor System VDPS was increased to include the following features A modification was designed to provide a real-time CRT display of selected VDPS parameters the AFCRL Linc Processor was interfaced with the VDPS a modification was made to reinsert silent frames into the output from silence-edited digital tapes as they are run in a tape input mode the capability of editing out the onset portions of words of speech in real-time has been added to the system. In addition, the results of studies on increasing VDPS flexibility and memory capacity are presented, to accommodate the research on the effects of speaker selection. Author
