The aim of the present study was to compare the phonological errors that occur in the speech of two 12-year-old Greek children with profound hearing loss. The first child used a cochlear implant (CI) and the second one used hearing aids (HA). The children's phonological development has been assessed using the Phonetic and Phonological Development Test (PPDT), (Levandi et al. 1995)1. In alignment with previous studies, the child with HA made more phonological errors than the child with CI, even though some unexpected findings were observed regarding the phonological processes used by both children.
