Auditory perception can be enhanced or interfered with by visual information from a speaker's face, but previous studies looking at whether tactile information influences speech perception have been limited. Here, by applying inaudible air puffs on participants' skin and thereby mimicking the tiny bursts of aspiration produced by certain speech sounds, it is found that syllables are more likely to be heard as aspirated, demonstrating that tactile information is also integrated in auditory perception.
