Our voice can reveal a lot about us: our age, our gender, and now — it seems — our height as well.
A new study by researchers at Washington University in St. Louis, University of California, Los Angeles, and Indiana University
found that listeners can accurately determine the relative heights of speakers just by listening to them talk. The key clue may be contained in a particular type of sound produced in the lower airways of the lungs, known as a subglottal resonance.
John Morton, study co-author and a psychology graduate student in Arts & Sciences at WUSTL, presented the study Dec. 3 at the 166th meeting of the Acoustical Society of America in San Francisco.
