A person鈥檚 style of speech 鈥� not just the pitch of his or her voice 鈥� may help determine whether the listener perceives the speaker to be male or female, according to a University of Colorado Boulder researcher who studied transgender people transitioning from female to male. The way people pronounce their 鈥渟鈥� sounds and the amount of resonance they use when speaking contributes to the perception of gender, according to Lal Zimman, whose findings are based on research he completed while earning his doctoral degree from CU-Boulder鈥檚 linguistics department.
