Zusammenfassung In this paper, we present a comparative overview of 9 studies on perceptual quality dimensions of synthetic speech. Differ-ent subjective assessment techniques have been used to evalu-ate the text-to-speech (TTS) stimuli in each of these tests: in a semantic differential, the test participants rate every stimulus on a given set of rating scales, while in a paired comparison test, the subjects rate the similarity of pairs of stimuli. Percep-tual quality dimensions can be derived from the results of both test methods, either by performing a factor analysis or via mul-tidimensional scaling. We show that even though the 9 tests differ in terms of used synthesizer types, stimulus duration, lan-guage, and quality assessment methods, the resulting perceptual quality dimensions can be linked to 5 universal quality dimen-sions of synthetic speech: (i) naturalness of voice, (ii) prosodic quality, (iii) fluency and intelligibility, (iv) disturbances, and (v) calmness
