A study was conducted of the development of consonant clusters in the phonology of a native English-speaking child. His progress was studied over a year and a half period, in three one-month segments. His speech was recorded by tape and transcribed. Techniques used to elicit consonant clusters included real word imitation, imitation of nonsense words, and adult imitation of the child. Rules for dealing with consonant clusters were abstracted from the data, and general phonological strategies were determined. Finally, predictions were made regarding the subject's future developmental phonological processes. (AM)
