Different voice qualities tend to vary in terms of their intrinsic
loudness. Perceptual experiments have shown that voice
quality variation can be strongly associated with the affective
colouring of an utterance. The question addressed in this
paper concerns the role that the intrinsic loudness variation
might play in this voice quality-to-affect mapping. To test the
hypothesis that the intrinsic loudness variation is not a major
determinant of the perceived affective colouring, listeners
rated the affective colouring of two series of stimuli: one
series varied in voice quality and contained intrinsic loudness
variation; the other series were of a constant voice quality, but
matched loudness variations of the first series. The results
overall support the hypothesis that loudness contributes
relatively little to the perceived affective colouring of specific
voice qualities. But variation in loudness (in the absence of
voice quality variation) is not entirely irrelevant: some
contribution of loudness to certain high activation affects was
