Development of the Prosodic Features of Infants' Vocalizing.
Lane, Harlan; Sheppard, William
Traditional research methods of recording infant verbal behavior, namely, descriptions by a single observer transcribing the utterances of a single infant in a naturalistic setting, have been inadequate to provide data necessary for modern linguistic analyses. The Center for Research on Language and Language Behavior has undertaken to correct this inadequacy. The Center collected permanent, complete, and continuous records of all vocalizations of two infants during their first five months of life. This data was then processed by new electro-acoustic techniques. In processing one hundred and eight 95-second vocal behavior samples, the computer determined (1) the number of utterances, (2) the duration of each utterance, and (3) the mean and standard deviation of the fundamental frequency and amplitude of each utterance. Further statistical analyses are now in progress. (WD)
