[Phenomenon of the accumulation of spectral information in vowel-like stimulus].

Studies have been made on the perception of vowel-like stimuli formed by interchange of impulses with various form of the spectrum following with a period of 14 ms. Application of similar stimuli in earlier investigations revealed a phenomenon of accumulation of spectral information during the interval within a stimulus and allowed to reject a hypothesis of averaging directly the auditory dynamic spectrum. In the first part of investigation, we checked and did not confirm a hypothesis of screening from the bulk of the accumulated data of those spectral configurations which are distinctly different from natural vowels. In the second part of investigation, new results were obtained which are predicted by the hypothesis of average meanings of vowel traits (calculated from impulse spectra) and which contradict the hypothesis of current phonemic discrimination with accumulation of the obtained values of similarity of the spectrum with phonemic standards.
