Abstract: The invention is associated with speech synthesis and with the producing of speech by electronic methods. The object of the invention is to create a new method e.g. for the modelling of the human speech mechanism's acoustic characteristics, i.e., of speech producing. The acoustic transfer function modelling the sound channel is approximated by subdividing it by mathematical methods into partial transfer functions of simpler spectral structure. Each partial transfer function is separately approximated by realizable rational transfer functions. The last mentioned rational transfer functions are realized, each separately, by means of equivalent electrical filters, which have been interconnected in parallel and/or series in the manner implied by the acoustic transfer function which is to be modelled. The models produced by the method of the invention may also be utilized in speech identification, in the estimation of the parameters of a speech signal and in so-called Vocoder apparatus. The invention is also applicable in electronic music synthesizers.
