Fundamental frequency (F 0 ) characteristics of non-distress vocalizations produced by four infants during the first twenty-four weeks of life were examined. This study constitutes the beginning of a longitudinal investigation of phonological development displayed by these children from birth to two years. Vocalization samples were obtained from home and laboratory recordings. Period-by-period F 0 melody plots and descriptive statistics for each utterance were derived from computer analysis. Mean F 0 centred around 335 Hz, with little variation evidenced when data were pooled. Duration, within-utterance range and variability did show developmental change. Individual F 0 fluctuations deviating from the mean were felt to be associated with the infant's state, activity levels, and changing vocal repertoire. Sources of variation among studies of infant F 0 characteristics appear to be related to differences in sampling and measurement techniques
