ABSTRACT:
Speech processing apparatus including a memory for holding prestored information indicative of different phonetic representations corresponding to respective sets of addresses in the memory. Circuitry in the apparatus electrically derives a series of coordinate values of points on a path in a mathematical space from frequency spectra of the speech occurring in successive time intervals respectively, identifies coordinate values approximating at least one position along the path of a peak in magnitude of acceleration, generates a memory address as a function of the position coordinate values and obtains from the memory the phonetic representation information prestored at that memory address. Methods and other apparatus for speech processing are also disclosed.
