By Jacob Aron LONELY vocalists can now perform a duet with an unusual partner – a pair of musical gloves that manipulate computerised sound to mimic the human voice. Gestures recreate the movements of real vocal chords, producing a complex range of sounds, though it takes about 100 hours to learn how to play the gloves, says Sidney Fels at the University of British Columbia in Vancouver, Canada, who led the research. The right-hand glove contains motion sensors that detect the opening and closing of the wearer’s hand. An open hand mimics the opening of the vocal tract, producing vowels, while a closed hand constricts the vocal tract to produce consonants such as “sh” and “zz”. Buttons on the left-hand glove activate stop consonants like “p” and “b”. These are normally produced by a sudden release of pressure, which is difficult to simulate using the right-hand vocal tract controls. A set of 3D position sensors on the right-hand glove locate the wearer’s hand in space,
