The program can be used as a special musical instrument 
or a voicing for Ukrainian text. It is not 
phonetically exact and proper, but it gives 
an inspiration to listen to the Ukrainian sounds more attentively.
It can be used by writers (especially poets) to compose melodic
texts. It can be used simply for the experiments. There is an
opinion that Ukrainian is a very melodic language, so you can
even not knowing it get some impression and get acquainted with
this beautiful language. There are a lot of songs in it and the 
program is intended to open some part of beauty of the language itself.
