Computer Generated Vocals

Question

Is this even possible? I.e. suppose you were given:

1) Lyrics to a song.
2) Background music of a song.
3) Timing of what syllables should be uttered when.
4) What note what each syllable should hit.

Given the above, is it possible to automatically generated the vocals via a computer program?

Thanks!

Answer 1

There is a commercial program out there that does this I think, though I haven't used it.

Answer 2

Yes, it is possible. For example, http://www.oddcast.com/technologies/sing/ It's a combination of speech synthesis and musical synthesizers.
