This study aims to analyze two processes related to two asymmetries in Brazilian Portuguese: vowel harmony and reduction in pre-stressed vowels. For so, acoustic analyses were carried out couched in coarticulation theories and a corpus, containing test and control words of high and low familiarity, recorded with 10 subjects from São Paulo and Pernambuco states. Here, we present the first results of a paulista female subject for F1, which is a correlate of vowel height. We show that familiar words are more in harmony with the stressed vowels considering pre-stressed vowels / e a o/ indistinctly.
