ABSTRACT Purpose To present and analyze the acquisition segmental curve of Brazilian Portuguese in simple and complex onset position and coda position. Methods 857 children with typical phonological acquisition participated in it, aged between 3:0 and 8:11, divided into age groups every 6 months. Participants were assessed using INFONO phonological assessment software. After analyzing the results, acquisition curves were drawn up for the segments analyzed in the different structures (simple and complex onset position and coda position). Results It was noted that, in simple onset position, some segments were acquired before 3:0 (stops, nasal and fricative, /f, v, s, z/. The /ʃ/ and /l/ segments were acquired at 3:0, /ʒ/ and /x/ at 3:6, /ʎ/ at 4:0, /r/ at 4:6; in coda position /N/ and /L/ were acquired before of 3:0, /S/ at 3:6 and /r/ at 4:6; in complex onset position, the structures composed by Fricative + /r/ and Stop + /r/ were acquired at 5:0, Stop + /l/ at 5:6 and Fricative + /l/ at 6:0. Conclusion Analyzing the acquisition curve is essential, as it provides a reference on the age of acquisition of segments in different syllabic structures. The acquisition curve contributes to the early identification of delays in phonological acquisition process enabling a timely referral for speech therapy intervention.
