摘要： Speech processing apparatus including an electronic memory and circuitry that derives from speech sets of digital values representative of frequency spectra. The spectra have peaks at frequencies associated therewith. The peaks include a highest magnitude peak for each spectrum. The circuitry also generates an auditory state signal representing the presence or absence of a burst-friction auditory state of the speech. Circuitry further electronically identifies, when the auditory state signal indicates the presence of a burst-friction auditory state, the highest magnitude peak for each spectrum as well as each peak having a magnitude within a range of magnitudes less than the magnitude of the highest magnitude peak, and selectively stores in distinct locations in the memory, respectively representative of normally occurring prominences of a burst-friction sound, the values of frequency of the lowest two frequencies associated with the identified peaks. Other speech processing apparatus and methods are also disclosed.
