Sensory Systems
When we speak, we do more than just create an acoustic signal. Rather, we generate a richly multimodal array of sensory consequences, including sight, hearing, and the many different somatosenses. We can show how listeners use this information to perceive speech. For example, when a listener feels a puff of air, they are more likely to think they heard /p/ than /b/ (Gick and Derrick, 2009). Sighted speakers move their heads more than speakers who have been blind since birth. When wearing a cloth or surgical mask (i.e. to reduce the spread of Covid-19), speakers accommodate for the acoustic impedance of their mask.
