This is a good indication that scientists still don't fully understand how the human voice works.Posted by jackhodgson at October 6, 2004 12:51 PMResearchers at King's College London and Phonologica Ltd. are using mathematical tools from quantum physics to address the problem. They have found that the vocal tract shapes sound waves in a way that is more complicated than conventional wisdom tells.
