This brief paper explores the potential of audio feedback in supporting better approaches to assessment, in particular formative assessment. Wimba Voice was deployed within a standard Virtual Learning Environment (VLE) application and was used as the basis for delivering audio feedback to students studying a level 1 web technologies module. The technology is described and the pedagogical impact of using audio feedback approaches is evaluated with controlled groups. The evaluation includes both quantitative and qualitative data and reveals enhancements to student learning and improvements to the "conditions" of "quality formative feedback"
