How do you visually represent different types of speech (whispering, shouting, etc.) within a dialogue box?

Visual cues can enhance the impact of speech. Whispering can be indicated by a smaller, fainter bubble and softer lettering. Shouting is represented with a larger, bolder bubble, often with jagged edges and all-caps lettering. Other techniques include using exclamation points or onomatopoeia within the dialogue, or visually amplifying the bubble's size.
