Based on previous studies, this paper aims 1° at checking a new model of superficial phonology annotation in tonal sequences dedicated to the analysis of the F0 prominence structure in words (INTSMEL), whatever the language type, tonal or not, 2° at using it in a semantic and a pragmatic approach of spontaneous dialogue. INTSINT and INTSMEL are both integrated in the Praat speech analysis software, the former dedicated to the annotation of intonation, the latter to that of lexical prominence
