Abstract:

Programs for processing speech waveforms to yield spectral analysis and phonetic segmentation have been under development on the FDP-Univac 1219 facility. Available outputs now include 1 homomorphic cepstrally smoothed spectra 2 a set of parameters extracted from the spectra 3 some preliminary segmentation markers 4 linear predictive coding coefficients, spectra, and formant estimates and 5 a fundamental frequency estimate. Current efforts are directed toward refining the segmentation algorithm. Implementation of the supporting software for the TX-2 Speech Data Base is proceeding. The TSPTerminal Support Processor hardware is now operating well enough to pass acceptance test, and emphasis is shifting from hardware checkout to system programming.
