Voice Interactive Analysis System Study. Final Report, August 28, 1978 through March 23, 1979.
Harry, D. P.; And Others
The Voice Interactive Analysis System study continued research and development of the LISTEN real-time, minicomputer based connected speech recognition system, within NAVTRAEQUIPCEN'S program of developing automatic speech technology in support of training. An attempt was made to identify the most effective features detected by the TTI-500 model speech preprocessor, and objective measures were used to demonstrate the presence of, and to evaluate, the various types of information used in LISTEN. Interword timing and structural peculiarities were the two most useful information sources for the two speakers investigated. Critical examination of the statistical models of the information sources revealed several ways to simplify and improve the LISTEN algorithm. Users manuals for analysis programs and for voice reference data generation programs are appended. (Author/CMV)
