The purpuse of this study is to search for verbal correlates of perceptual dimensions of musical timbre. In a previous experiment, we extracted 23 most often used verbal attributes from spontaneous verbalizations describing similarities and differences between pairs of timbres and we tried to compare their use with the relative positions of timbres along each perceptual dimension. In this experiment, we used a VAME paradigm to test more quantitatively these verbal attributes. 12 synthetic sounds were presented and rated on each of the 23 unipolar semantic scales. The results showed a good agreement between subjects. We found 4 principal verbal correlates for each perceptual dimension : "pas soufflé" (not blown), "pincé" (plucked) "attaque rapide" (fast attack) and "résonnant" (resonant) for the attack time dimension, "rond" (round), "grave" (low/deep), "pas haut" (not high/sharp/shrill), "large" (wide) for the spectral centroïd dimension; and "riche" (rich) for the spectral fine-structure dimension.
