This paper explores the mapping of voice quality to affect, for a synthesised tense - lax voice continuum. Two questions are of interest. Firstly, over such a continuum, do listeners' attributions of affect change in a continuous or in a more categorical way? Secondly, might discreetly different affects emerge at different points in the continuum: specifically, might a moderately tense voice cue happy? Note that extremely tense does not appear to, but seems rather to be associated with the affect angry. A continuum of stimuli were synthesised ranging from a very tense quality at one end to a very lax quality at the other. Listeners rated their affective colouring in terms of the pairs of affective attributes: stressed/relaxed, angry/content, happy/sad, interested/bored, formal/intimate, and indignant/apologetic. Results suggest that, for these voice qualities, listeners' attribution of affect is essentially continuous. Furthermore, moderate tension does not evoke happy.
