The individual properties of the human voice are very well detectable and measurable using a number of computer programs, which are based on the principle of spectral analysis. Especially in recent years, major workplaces in the Czech Republic and abroad are engaged in research of the human voice and especially the creation of software for the analysis of the main voice parameters. Computer programs based on spectral analysis would be an ideal tool for the voice educator and especially the voice therapist to find objective information about the quality of the voice and voice of individual students or about the effectiveness of his pedagogical or therapeutic intervention.
