Audio Emphasis Level

A sonification technique that represents the degree of visual emphasis applied to text (such as larger font size, bold styling, or color changes) using distinct audio cues layered onto speech output. For example, strongly emphasized text might be accompanied by a bell ringing sound while weakly emphasized text triggers a lighter tinkling sound. Audio emphasis levels allow blind users who are listening to web content via speech synthesis to perceive the visual text hierarchy and emphasis that sighted users recognize at a glance through font styling and size differences.
