[The role of amplitude modulation in forming the auditory images of speech signals].
The identification of stationary vowels in influenced by the change in relations of formant amplitudes as if their "centre gravity" is used in phoneme decision. That is valid for formants spaced in critical frequency band equal approximately 3.5 Bark. The hypothesis about large-scale spectral integration in auditory system is based on this effect. The data obtained supports the hypothesis in respect to non-stationary sounds, too. Imitation of the large-scale spectral integration on the model of auditory processing suggests that the frequency band of the integration may be equal to 3.5 Bark.
