The purpose of this study was to examine vowel production in 7- to 12-month-old infants with hearing loss. Fifty-four infants were divided into three groups according to degree of hearing loss (mild-to-moderate, moderately severe-to-severe, profound), and their vocalizations were phonetically transcribed from 30-minute videotaped samples. These transcriptions were analyzed to determine the percentage of infants in each group who produced the various English vowel phones. Results showed that vowel acquisition patterns in infants of this age with all degrees of hearing loss were similar to those of children of the same age with typical hearing. Established production of the /i/ and /e/ vowels was seen only in the mild-to-moderate hearing loss group, which may demonstrate the emerging role of auditory feedback in vowel production. Findings are discussed in terms of clinical implications and directions for future research.
