Praat is an open source software that can be used to analyze almost any audio data.
Synthesizer V users mostly use it when they make covers of songs, you can extract vocal data (phrasing, intonation and whatnot) from the original and apply it to a Synthesizer V singer.
You can also use your own voice (singing that cover) to modulate a virtual singer.
In my opinion, a waste of time for people who write original songs.

Any voice (from the ones available). Not all voices (of the ones available).
