The term 'Speech Bobbles' refers to the small, cartoon-like bubbles that are used to represent dialogue in comic books and graphic novels. The acronym ERS stands for 'Expressive Representation System, ' which is a type of software used to create these speech bubbles. This software allows artists to quickly and easily create speech bubbles with different fonts, colors, and sizes, making it easier to convey dialogue in a visually appealing way.
