This paper investigates the relationship between perceptive and acoustic spaces describing a group of voices. The aim is to study possible correlations between prosodic parameters and the perceived quality of voices. Experiments are based on a set of 100 sentences recorded by 20 professional female speakers. A perceptual experiment aims at defining a set of relevant adjectives (or "attributes") for voice quality description (20 attributes are retained). Acoustic prosodic analysis is performed on the same corpus (23 parameters are used; mainly based on pitch, durations and energy). Then correlations between acoustic parameters and perceived attributes are computed. The results show that for some attributes, one can find a strong correlation with prosodic acoustic parameters (for about 13 attributes out of 20). However, for some attributes, these correlations are rather low, and more detailed investigations seem necessary in order to characterize perceived attributes in terms of acoustic parameters.
