The researchers had subjects listen to spoken syllables while hooked up to a device that would simultaneously blow a tiny puff of air onto the skin of their hand or neck. The syllables included "pa" and "ta," which produce a brief puff from the mouth when spoken, and "da" and "ba," which do not produce puffs. They found that when listeners heard "da" or "ba" while a puff of air was blown onto their skin, they perceived the sound as "ta" or "pa."
