We are all capable of "hearing" shapes and sizes and perhaps even "tasting" sounds, according to researchers.
This blending of sensory experiences, or synaesthesia, they say, influences our perception and helps us make sense of a jumble of simultaneous sensations.
Oxford University scientists found that people associate lower-pitched sounds with larger and more rounded shapes.
One of the team is now working with chef Heston Blumenthal to incorporate words into a new dining experience.
Synaesthesia itself is a rare and unusual condition thought to affect less than 1% of the population.
