摘要：In this work it is investigated quantitative and qualitatively the emergence of liquid consonant /l/ in a child’s speech in Brazilian Portuguese as their L1, which was longitudinally observed between 1:9 (one year and nine months) and 2:4 (two years and four months). In order to do so, thirty-four productions related to the word /eSˈtɾela/ were analyzed and five variants of execution were verified, namely: [ˡteɐ], [ˡtejɐ] [ˡtejlɐ], [ˡteʎɐ] and [ˡtelɐ]. Each of these variants was analyzed qualitatively based on the trajectory of the formants and the intensity of the sounds showed by the spectrograms; and quantitatively, through the analysis of the values of formants’ frequencies and especially by the difference between F2 and F1, necessary to verify the degree of posteriorization of the lateral produced. From the analyzes, gradients were observed in the subject's speech in an attempt to reach the target — the lateral alveolar. These gradients could only be verified on the basis of the acoustic analyzes detailed here. Values resulting from the difference between F2-F1 revealed that the distance between the two subjects decreased as productions approached their target because it was verified that when the difference between these two formants decreases the productions approach the lateral alveolar. --- DOI: http://dx.doi.org/10.12957/matraga.2017.28509
