Currently, there is a lack of usable, remote, and accessible voting technologies that must be addressed. An interactive voice response (IVR) system is one potential solution to this problem, due to its capability of remote use and its audio interface, which is very beneficial for those who are visually impaired. An IVR voting system developed by Holmes and Kortum (2011) was fitted with a synthetic voice and an audio speed adjustment feature for increased accessibility and usability, especially for blind voters (Piner, 2011). This system was tested on the three ISO 9241-11 usability metrics (ISO 9241-11, 1998), efficiency (time to complete a ballot), effectiveness (accuracy), and satisfaction (subjective usability) and compared with the usability of other voting methods in an attempt to determine its viability as a voting method. The usage of the accessibility feature was also examined. Results showed that the IVR voting system is comparable with other voting methods in terms of usability. Results also showed a noticeable portion of non-visually impaired participants utilized the accessibility feature.
