Annotation: This article details the development of methods for the synthesis of phonemes of the human voice based on the analytical description of individual formants. A technique for analyzing the spectrum and spectrograms of original phonemes to obtain the main amplitude-frequency characteristics of the signal components is presented. An algorithm to reconstruct a speech signal based on the obtained sets of parameters is proposed. A technique to assess the quality of synthesized speech elements is described.

Keywords: speech synthesis, spectrum, spectrogram, phoneme, formant, amplitude-frequency characteristic
