Siegel, Gerald M.; And Others – Journal of Speech and Hearing Research, 1990
Ten infants aged 8-12 months were studied to determine whether they would spontaneously imitate the average fundamental frequency or fundamental frequency contour of their speaking partners. Acoustic analyses failed to reveal any tendency by the infants to adjust vocal pitch, amplitude, or duration in home or laboratory settings. (Author/JDD)
