The paper points to problematic and usually neglected aspects of using listening tests for TTS evaluation. It shows that simple random selection of phrases to be listened to may not cover those cases which are relevant to the evaluated TTS system. Also, it shows that a reliable phrase set cannot be chosen without a deeper knowledge of the distribution of differences in synthetic speech, which are obtained by comparing the output generated by an evaluated TTS system to what stands as a baseline system. Having such knowledge, the method able to evaluate the reliability of listening tests, as related to the estimation of possible invalidity of listening results-derived conclusion, is proposed here and demonstrated on real examples.
