Voice Usability

The degree to which a web page, application, or document is usable when accessed through a voice browser or screen reader — the audio-first counterpart to traditional visual usability. Voice usability combines structural quality (navigability — how quickly a user can reach meaningful content) with speech-output quality (listenability — how well the rendered text reads aloud). It depends not only on accessibility-markup conformance but on meaningful ALT text, predictable heading and landmark structure, reasonable reading order, and the absence of tricks (space-separated characters, redundant link labels, nested tables for layout) that degrade speech synthesis or force the listener to re-scan content.
