Singing Lyrics
It would be nice if Musescore could sing the lyrics typed in the scores.
I know that this is possible by editing the configuration file instruments.xml and adding a soundfont containing vocal samples into the "sound" folder. But this way of operation is very complicated.

Actually, it's not even possible that way. A soundfont will only make a single sound for each note. So you could have a soundfont that always sang the word "love" every time the note G came up, for instance, but it couldn't sing different words, and certainly wouldn't have every word in the language. What you are talking is way way way beyond a soudnfont, it's a whole separate AI program. And there are programs that can attempt this. So, I recommend investigating the possibilities there. I believe if you export your score to either MusicXML or perhaps MIDI, some of those AI programs might be able to use that info.

Vocaloid at least can use MIDI files as inputs, though you'll have to re-enter the lyrics in the actual software. UTAU can also take MIDI files from what I've seen, though I personally only have experience with Vocaloid. Either way, as Marc said, there's no way to do this directly in MuseScore.
