Abstract

The speech interface development per se is not a guarantee of quality for the accessibility to visually impaired users either to as much of a website as possible where it can be achieved or to as much of functions a stand-alone product can provide. In this paper, a methodological approach for assessing accessibility problems in voice user interfaces (VUI) is proposed, which includes uncertainty treatment by using Bayesian networks. A case study is discussed, in which the proposed approach has provided encouraging results, and seems to have a potential to be successfully applied to other similar speech stand-alone software applications.
