Aspartame is an artificial sweetener that is often used as a sugar substitute in many foods and beverages. Aspartame is about 200 times sweeter than common sucrose and is used because it can add a strong sweetening effect with fewer calories compared to sugar. This is due to the low quantity of aspartame needed to create a sweet flavor.
The pronunciation of aspartame varies between American and British English.
In American English, the correct pronunciation of aspartame is AH-spur-tame.
The main difference in pronunciation between the two is which syllable is stressed. In American English, the stress must be pronounced on the first syllable, -AH. The stress on the first syllable causes the rest of the word to be pronounced as -spur-tame
Differently from the US pronunciation, the British pronunciation of aspartame places the stress on the second syllable
