Abstract:
The model for spectrum transformation in the auditory analyser consists of three layers: that of filters whose parameters imitate the masking curves; that of non-linear transformers, the non-linearity parameters being chosen in such a way that the calculation results would correspond to the basic regularities of perception of stationary signal loudness; that of lateral inhibition. The weight function parameters of the latter were chosen according to a psychoacoustical experiment. By means of such a model the formant structure of the sound can be distinguished in a synthetic speech-like signal; at low frequencies to 1000 Hz besides formants the first harmonics are distinguished.
