Myriad software has "the virtual singer" packaged with its PDF-to-Music Pro. Maybe a partnership is worth pursuing? Granted it's quite robotic, like 1990s general MIDI, but would be helpful.

Excellent suggestion! Maybe there's a script or plugin that could accomplish this after the notes have been entered.
