I have been trying to determine how close the Internet is to being 
able to produce, approximately, a "Multi-Lingual Singing Student"?
What I have in mind is some singing device where a teacher/programmer
could give an instruction set ~ "your sound output would be improved
if you could adjust you output to be more in accord with the sound/text
sample I will here input". The teacher then gives the student an audio
file and a text file that corresponds. The student analises both and
and mathematically adjusts, "morphs?", by some declared ratio, output.
A second pass would bring about an even closer accord, etc.
