Abstract : The relations between production and perception in 4-year-old children were examined in a study of compensation strategies for a lip-tube perturbation. Acoustic and perceptual analyses of the rounded vowel u produced by twelve 4-year-old French speakers were conducted under two conditions: normal and with a 15-mm-diameter tube inserted between the lips. Recordings of isolated vowels were made in the normal condition before any perturbation N1, immediately upon insertion of the tube and for the next 19 trials in this perturbed condition, with P2 or without articulatory instructions P1, and in the normal condition after the perturbed trials N2. The results of the acoustic analyses reveal speaker-dependent alterations of F1, F2, and-or F0 in the perturbed conditions and after the removal of the tube. For some subjects, the presence of the tube resulted in very little change; for others, an increase in F2 was observed in P1, which was generally reduced in some of the 20 repetitions, but not systematically and not continuously. The use of articulatory instructions provided in the P2 condition was detrimental to the achievement of a good acoustic target. Perceptual data are used to determine optimal combinations of F0, F1, and F2 in Bark related to these patterns. The data are compared to a previous study conducted with adults Savariaux et al., J. Acoust. Soc. Am. 106, 381-393 1999.
