Speech

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 TSP(Terminal Support Processor) hardware is now operating well enough to pass acceptance test, and emphasis is shifting from hardware checkout to system programming.
