That is the voice of a man who has been dead 3,000 years. Nesyamun was an Egyptian priest who lived during the lived during the volatile reign of pharaoh Ramses XI (c.1099–1069 BCE), and worked as a scribe and priest at the state temple of Karnak in Thebes (modern Luxor). When he died, he was mummified so he could live forever.
Enough soft tissue was preserved by the process that scientists could make a 3-D printing of his vocal tract. They hooked it up to a speech synthesizer and…voila! Although all you hear is a single vowel, and it sounds like Nesyamun’s voice if he spoke lying on his back (as he was when the vocal tract was mummified), it still represents a huge step for science.
