<p>It has
recently been reported in the synesthesia literature that graphemes sharing the
same phonetic feature tend to induce similar synesthetic colors. In the present
study, we investigated whether phonetic properties are associated with colors
in a specific manner among the general population, even when other visual and
linguistic features of graphemes are removed. To test this hypothesis, we
presented vowel sounds synthesized by systematically manipulating the position
of the tongue body’s center. Participants were asked to choose a color after
hearing each sound. Results from the main experiment showed that lightness and
chromaticity of matched colors exhibited systematic variations along the two
axes of the position of the tongue body’s center. Some non-random associations
between vowel sounds and colors remained effective with pitch and intensity of
the sounds equalized in the control experiment, which suggests that other
acoustic factors such as inherent pitch of vowels cannot solely account for the
current results. Taken together, these results imply that the association between
phonetic features and colors is not random, and this synesthesia-like
association is shared by people in the general population.</p>
