In this dissertation, I have analyzed the oral and orthographic production of the variable diphthongs [aj] and [ej] in Brazilian Portuguese (BP) by a group of fifteen children who were developing their literacy processes in an Elementary School in Pelotas, RS. My main objective was to describe the oral and written production of such vowel sequences and, based on comparisons found in the collected material, to provide arguments not only for the discussion about the phonological representation of those sequences but also for the proposal of child representation restructuring based on how they learn to write. In order to achieve this objective, I presupposed that children‟s oral production and their early orthographic productions of the diphthongs under investigation, collected for two years in a row, could provide clues to comprehend these children‟s phonological knowledge of those vowel sequences. Data analysis showed that, regarding oral production, the first graders produced very low frequencies around 5% - of both diphthongs whereas second graders yielded 63% for [aj] and 44% for [ej]. Concerning orthographic productions, data analysis showed that, at the beginning of their literacy processes, children tend to have some difficulties regarding conventional writing in terms of spelling both vowel groups since they prefer forms without the semivowel. Besides, in subsequent stages, an important change was perceived in the children‟s orthographic development: around 80% for the production of the grapheme i‟, which seems to evidence that these orthographic structures have already been acquired by second graders. On the whole, the data, along with further arguments regarding the diphthongs in variation and oral acquisition, provided arguments to make me suggest that children spell such segments as if they had one vowel only in the subjacency, /a/ and /e/, in accordance with the input they got, rather than as a structure vowel + glide, which would be produced in the following stages, when they learn how to write. This interpretative proposal is supported by the fact that children are acquiring the phonology of their language in a successive process of (re)construction of their phonological representations while their orthographic systems are being built. Based on the data collected by this study and a set of data on the acquisition of such segments, I questioned whether palatal fricatives are complex segments in child phonology and proposed an interpretation for the utterance of the phonetic diphthongs [aj] and [ej] which says that the children under study interpreted the palatal fricative consonants, in their early phonological development, as simple segments and modified their interpretation due to the learning of the alphabet writing.
