I experience sound to taste synaesthesia which means every sound I hear has a flavour automatically attached. This taste connection isn’t an association, It’s an actual mouth feel made up of flavour, texture, volume and temperature and appears as a burst of taste landing on different parts of my tongue. It’s also consistent over time - the synaesthetic sound tastes I experienced as a child are the exact same ones I experience today. This affects all sounds I hear but the most powerful reactions are triggered by word sounds, labelled Lexical Gustatory Synaesthesia. Whenever I hear words or indeed read words (because I hear words as inner speech as I read them), the vast majority trigger a synaesthetic flavour that ranges from the very intense down to words that produce only faint taste sensations. The actual sensation is similar to that of turning a light bulb on and off, it suddenly appears, and then fades away, sometimes quickly, sometimes very slowly, depending on the strength of the reaction. These flavour sensations can’t be controlled, they’re automatic and neither can they be turned off or down and are always coming and going in a relentless stream.
