This work aims to investigate, from the perspective of the Acoustic Theory of Speech Production, the occurrence of palatalization of alveolar nasal from the analysis of speech data of three women born in União dos Palmares. Considering that most of the studies on palatalization in Brazil are devoted to analyzing the stops / t, d /, this study has its relevance, since it is dedicated to another segment susceptible to this process. The data was analyzed using the PRAAT computational application to describe the visual parameters in order to describe the visual parameters from the observation of the trajectory of the formants in the spectrum that can be interpreted as a lane for the point of articulation. In addition, using the R program package, we analyzed if are difference in distribution of values of frequencies of F1, F2 e F3 and we observe the interference of adjacent contexts to the alveolar nasal in the palatalization process. The results indicated the occurrence of three variants, namely: [n], [nʲ] and [ɲ]. The distinction of the variants was obtained from the observation of the frequency relation of F2 and the other frequencies, as the more the tongue approaches the palatal region, the more F2 increases. As for the influence of the phonetic environment, the upper segments seem to favor the process.
