A large number of methods for measuring of audible discontinuities, which occur at concatenation points in synthesized speech, have been proposed in recent years. However, none of them proved to be comparatively better than others across all languages and recording conditions and the presented results have sometimes even been in contradiction. What is more, none of the tested concatenation cost functions seem to be reliably reflecting the human perception of such discontinuities. Thus, the design of the concatenation cost functions is still an open issue, and there is a lot of work remaining to be done. In this paper, we deal with the problem of preparing the test stimuli for evaluating the performance of these functions, which is, in our opinion, one of the key aspects in this field.
