I went and looked at your page.

They are probably selling a program, must programs cost today.
Haptars lipsync sound so the trick is separating word sound from music sound.
Once separated doesn't people putty convert wave to lipsync ogg? I'm not sure as I don't have putty
Anyway you need separation program and patience. Each word has music sound to separate. I never got into it, don't have the patience. One song is many hours.
A neat trick is to get a acapella song, (a song with vocal alone). No separation needed. There are some on youtube. Or you or your wife could sing a song?
