This longitudinal study investigated the continuity of acquisition of the English consonant inventory from babbling to sound-bysound correspondences with the adult form in 5 children with chronic otitis media (COM). Language samples were examined to determine consonants produced from ages 10-21 months. Results showed that consonants in babbling were the first to appear in quasi-words and to be used correctly relative to the adult form. In 4 of the children, babbling inventories contained glides, nasals, and labial and coronal stops. Subsequent acquisition followed patterns reported for normal development. One child used an atypical babbling inventory (dorsals and glottals) in quasi-words and did not produce any real words until age 21 months. Results of audiologic testing, pneumatic otoscopy, and tympanometry indicated this child had the highest mean hearing thresholds and the most bouts of otitis media. Results suggest a relationship among COM, hearing and early phonetic development.
