This study investigates the phonological acquisition of Brazilian Portuguese (BP) by a group of 24 bimodal bilingual hearing children, who have unrestricted access to Brazilian Sign Language (Libras), and a group of 6 deaf children, who use cochlear implants (CI), with restricted or unrestricted access to Libras. The children's phonological system of BP was assessed through the Naming Task (Part A) of the ABFW - Children Language Test (ANDRADE et al. 2004). The results revealed that the hearing children and the deaf child who use CI, all with full access to Libras, showed expected (normal) phonological acquisition considering their age groups. We consider that the early acquisition and unrestricted access to Libras may have determined these children's performance in the oral tests.
