Parameters are proposed that characterize the form of individual signals of a speech file, such as the position of quantiles in a selected fragment and the parameters of parabolas that approximate the area under a curve. It is shown that the distribution of these parameters can be used for automatic discrimination of files containing speech in Tatar and Russian languages.
