Abstract: There are many procedures to describe F0 contours in acoustic-phonetic terms. Garrido's (1996, 2001, 2010) and z-score normalization systems have the advantage that they are automatic procedures. Therefore, this paper aims at analyzing both systems in order to determine the possible future application for the analysis of Spanish as a Foreign Language spoken by Brazilians (SFL). To do so, we analyze the melodic curves in declaratives, yes-no questions and wh-questions in Madrid Spanish, in Brazilian Portuguese (BP) spoken in the city of São Paulo and finally, in SFL. The validity of both systems was tested through a perception test with 10 Brazilian and 10 Spanish listeners. Listeners rated the degree of similarity between the signals with original intonation and signals with stylized F0 contours. The results showed that Garrido's automatic stylization method is really able to perceptually create representations equivalent to the original ones in Spanish, BP and SFL and also better than those obtained with the procedure based on z-score normalization.
