In the present study, three aspects of the 2-month-old’s perception of multisyllabic utterances were explored. First, do infants perceive phonetic contrasts occurring either in the initial (Bada-Gada) or medial (Daba-Daga) positions of multisyllabic utterances? Second, are infants more likely to perceive these contrasts in stressed as opposed to unstressed syllables? Third, will infants detect a difference between two stress patterns? Our results indicate the following: (1) Two-month-olds are sensitive to place-of-articulation differences occurring in either the initial or medial positions of multisyllabic stimuli. (2) Whether the contrast occurred between stressed or unstressed syllables had little or no effect on the infant’s ability to detect it. (3) Infants as young as 2-months old respond to differences between stress patterns.
