Voice of a 3,000-year-old Egyptian mummy reproduced by 3-D printing a vocal tract

The mummy underwent a CT scan at Leeds General Infirmary as part of the study.

(CNN)Scientists have revealed what the voice of a mummified Egyptian priest who lived 3,000 years ago would have sounded like by 3-D printing his vocal tract.

The team were able to accurately reproduce a single sound, which sounds a bit like a long, exasperated "meh" without the "m."
David Howard, one of the academics behind the project, describes it as falling somewhere between the vowels in the English words "bed" and "bad."

    "The sound you hear is the sound of his vocal tract in the position he is lying in the sarcophagus," said Howard, who is professor of electrical engineering at Royal Holloway, University of London.
    Howard has already reproduced the vocal tracts of living people, including his own, using this same method and found that the sounds produced were very realistic. However, this is the first time the technique has been applied to human remains. The results were published Thursday in the journal Scientific Reports.

    Sound, not speech

    The team chose the mummy of the Egyptian priest Nesyamun from the Leeds City Museum in the UK because the soft tissue in the throat and vocal tract was reasonably intact. Their technique doesn't work on skeletal remains.
    The team took the mummy to the Leeds General Infirmary, where it underwent a CT scan in 2016 to gain all the measurements necessary to reproduce the vocal tract, which curves from your larynx to your lips.
    Computer software was then used to identify the airway, which was 3-D printed using plastic similar to that used to make Lego bricks. The printed airway was then connected to a specialized loud speaker as well as an artificial larynx commonly used to make electronic speech, through which the sound plays. What came out was the vowel sound.
    Howard cautions that the sound they reproduced is just the sound of his voice and isn't the Egyptian priest actually speaking -- although this is something that might be possible in the future to revolutionize how we connect with the past.
    "It's not, in fact, a sound he would ever likely have made in practice because the bulk of his tongue isn't there," he told CNN.
