Dr Matsumi Suzuki, who generally uses his skills to help with criminal investigations, measured the face and hands of Leonardo da Vinci's famous 16th century portrait to estimate her height at 168 centimeters (5 feet, 6 inches) and create a model of her skull.
"Once we have that, we can create a voice very similar to that of the person concerned," Suzuki told Reuters in an interview at his Tokyo office last week.
"We have recreated the voices of a lot of famous people that were very close to the real thing and have been used in film dubbing."
The chart of any individual's voice, known as a voice print, is unique to that person and Suzuki says he believes he has achieved 90 percent accuracy in recreating the quality of the enigmatic woman's speaking tone.
Speaking of M.L., I've always enjoyed this song, sung by the incomparable Nat King Cole.
In the comments: I've been asked to explain my love for NKC's "Mona Lisa." I guess it's because of the haunting melody and the line "do you smile to tempt a lover, or is this your way to hide a broken heart." I've done that - smile when my heart hurt, that is. I've only had my heart broken by a woman one time, and that was in college (and, no, it wasn't by The Wife).
