Multisyllable babbling lies at the interface between prelinguistic and linguistic behavior. The purpose of this study was to examine two unresolved issues related to multisyllable babbling. The first issue was derived from models of infant vocal development which suggest systematic increases over time in the amount of phonetic variation within multisyllable babbles. The second issue of concern in this investigation involved final syllable vowel lengthening in infant vocalizations. This phenomenon has been well documented in adult spoken English, as well as other languages, but has been the subject of disagreement in studies of infant vocalizations.Subjects--Topical Terms:

520 $a Multisyllable babbling lies at the interface between prelinguistic and linguistic behavior. The purpose of this study was to examine two unresolved issues related to multisyllable babbling. The first issue was derived from models of infant vocal development which suggest systematic increases over time in the amount of phonetic variation within multisyllable babbles. The second issue of concern in this investigation involved final syllable vowel lengthening in infant vocalizations. This phenomenon has been well documented in adult spoken English, as well as other languages, but has been the subject of disagreement in studies of infant vocalizations.
520 $a This investigation was designed to address two major questions: (1) Do later multisyllable vocalizations contain greater phonetic variation than those produced at earlier ages? (2) Is final syllable vowel lengthening characteristic of infant bisyllable vocalizations? Eight infant subjects were audio tape recorded in their homes at ages seven, nine and eleven months. The samples yielded 480 multisyllable vocalizations, which were categorized based on presence or absence of phonetic variation, and the source of that variation (place change, manner change or both). Systematic increases in phonetic variation in the multisyllable vocalizations was not characteristic of the majority of infants studied. Multisyllables were produced with phonetic variation at or near the beginning of multisyllable babbling, which failed to support the existence of distinct stages of repetitive (multisyllables with nonvaried phonetic elements), and nonrepetitive (phonetically varied multisyllables) babbling.
520 $a The issue of final syllable vowel lengthening was examined by analysis of the 95 bisyllable vocalizations present in the multisyllable data set. Duration measurements were made of each syllable nucleus (vowel portion) using computer assisted acoustic analysis. A repeated measures planned comparison of the duration of the first syllable nucleus compared with the second indicated that the second syllable nucleus was significantly longer. The results suggest that final syllable lengthening is not a primarily learned behavior.
