Abstract :
A histogram of the minimum value of F2-F1 for /a/ from TIMIT (limited to alveolar consonantal context), shows a maximum at 3-3.5 Bark and clear asymmetry. This is interpreted as evidence of auditory perceptual control of /a/ during continuous speech. Trajectories of individual vowel tokens of /a/ in other contexts in F 1/F2 space also show striking changes at this line, which coincides with the Chistovich critical distance between formants
