Abstract

Several issues show in the test management during the test of voice user interfaces. This is due to differences between the test of voice user interfaces and graphical user interfaces. The main reason is the diversity of input possibilities by spoken or written language. In addition, it is not clear, how the accuracy of voice user interfaces can be measured. Requirements and acceptance criteria must be defined of the start. Furthermore, it is challenging to find suitable spoken utter-ances for a test to comprise the wide range of linguistic possibilities. Eventually, it must be cleared, how tests with this wide range of utterances can be automatized in a way to serve both value-adding and risk oriented. These points are described in this article and solution possibili-ties are shown.
