Mel-cepstral characteristic coefficients are better suited for solving our problem. Since the neural network strongly depends on its structure, the results may change with the increase in the volume of input data and the number of languages. But at this stage, it was decided to use only mel-cepstral characteristic coefficients with normalization.enmel-cepstral characteristic coefficientsspectrogramtime maskfrequency maskneural networkvoiceaudio seriesArticlehttps://doi.org/10.30837/ITSSI.2023.26.016
